As an excellent solvent, dimethyl sulfoxide is often used as a green solvent substitute in chemical synthesis. It dissolves many organic and inorganic compounds, including difficult-to-dissolve polymers, allowing some reactions to take place under milder conditions. Due to the continued growth in global demand, especially driven by the pharmaceutical industry and electronic materials industry, the DMSO market is expected to reach more than $150 million.1. ApplicationMedicine: Dimethyl sulfoxide is also a useful pharmaceutical ingredient. It can promote drug absorption and penetration of the skin, so it is often used in drug anti-reflection agents, drug delivery agents and local anesthetics. Dimethyl sulfoxide is also used in biomedical research and in the manufacture of pharmaceutical intermediates.Metalworking: dimethyl sulfoxide can also be used as an additive in metalworking fluids for cleaning, polishing and corrosion prevention of metal surfaces.Electronic materials: dimethyl sulfoxide is more and more widely used in electronic materials. It can be…

The difference between pharmaceutical intermediates and apis Pharmaceutical intermediates and apis both belong to the category of fine chemicals. Intermediates are materials produced in the process steps of apis that must undergo further molecular changes or refining to become apis. Intermediates can be separated or not separated. (Note: This guide covers only intermediates that the company defines as being manufactured after the start point of manufacturing for the API.) Active pharmaceutical ingredient (API) : Any substance or mixture of substances intended to be used in the manufacture of a pharmaceutical product and, when used in a pharmaceutical product, becomes an active ingredient of the pharmaceutical product. Such substances have pharmacological activity or other direct effects in the diagnosis, treatment, symptom relief, management or prevention of disease, or can affect the function and structure of the body. An active drug is an active product that has completed the synthetic path, and…

1. Dispersion technologyWhen producing colored paints, good dispersion quality is one of the most difficult factors. The dispersion process involves converting the dry pigment into a pigment dispersion, which must be fully dispersed and stable enough to achieve the final color performance and stability. This is a complex process in which the use of resins, pigments, solvents and dispersants play an important role.2. Dispersion processHigh-quality coatings with high saturation and coloring power are characterized by good pigment dispersion, optimized pigment particle size and long-term stability.In liquid coatings, the dispersion process of pigments can be divided into three processes: dispersion process Pigment wetting: The air and moisture covering the pigment is replaced by a resin solution. The solid/gas interface (pigment or air) is converted into a solid/liquid interface (pigment or resin solution).Grinding stage: The pigment clumps through high shear forces are broken down into smaller units, preferably primary particles.Stabilization: The pigment…

thickenerThe raw material of latex paint is affected by the performance of the product, and only the thickener has a wider impact on the manufacturing, storage and transportation of latex paint, construction, and coating performance.1. Rheological properties of latex paintThe viscosity of latex paint is dependent on shear force and time, and with the increase of shear force or the extension of shear time, the viscosity of latex paint will change, which is the rheological property of latex paint. The viscosity of latex paint has an effect on the settling property, brushing property, film fullness property, leveling property and the fluidity of the paint on vertical surfaces. The different rheological physical property curves of paint from storage to application are shown in Figure 3. Latex paint must undergo such rheological process during storage and construction. The viscosity control of this process depends on the combination of different types of thickeners…

Two-color photosensitive laser Direct writing (TCS-DLW) is a novel nanolithography technique, which can break the optical diffraction limit and directly realize the fabrication of arbitrary 2D/3D micro-nano structures with sub-hundred nanometer resolution. Organic polymer photoresist is a medium and carrier for micro and nano fabrication by two-color photosensitive laser direct writing technology, which directly affects the precision and authenticity of the micro and nano structures. Recently, Chinese scientists developed a polyvinylpyrrolidone (PVP) hybrid two-color photoresist. PVP has good compatibility with the active monomer of photoresist, which can improve the mechanical strength of photoresist, increase the conversion rate of polymerization monomer and reduce the polymerization threshold. The introduction of PVP also reduces the volume shrinkage of the photoresist from 18% to 3%, greatly reduces the internal stress of the fabricated micro and nano structures, and improves the accuracy of the lithography and the authenticity of the micro and nano structures. Compared…

The chemical industry should balance short – and long-term goals to deal with the uncertainty of the current situation and prepare for the future. After a challenging 2022, many in the chemical industry expect a modest rebound in production in 2023. By mid-2023, however, several chemical companies had slashed their forecasts. A number of factors have led to weak global demand for chemicals, including the economic recession in Europe, inflation in the United States and a smaller-than-expected rebound in demand in China. In addition, overordering in 2021 and 2022 led to high inventory levels, leading to months of destocking. As a result, chemical production in the first eight months of 2023 increased by less than 1% year-on-year, with production declining in many market segments. 2 Many companies have shifted their focus to reducing costs and improving efficiency to help offset the decline in production. In the United States, recession fears…

Chemical companies’ attention has shifted from demand issues to more sustainable practices in an effort to address rising production and transportation costs, greater demand to reduce carbon footprint, diminished profitability, and the push to develop more recyclable products. The U.S. chemical industry is undergoing a profound transformation in 2023, embarking on a journey of portfolio refinement, supply chain optimization, and groundbreaking material innovation. This transformative shift is fueled by a resounding call for circularity, decarbonization, and sustainability, marking a pivotal moment in the industry’s history. It represents a significant reset, as companies reassess their material utilization practices aligning with evolving customer demands, encompassing not only the products they offer but also the diverse pathways and feedstock choices they embrace. The disruption experienced over the past three years has underscored the importance of localizing supply chains and striking a balance between efficiency and resilience. The path forward could initiate a shift…

Since the beginning of this year, the prosperity of the chemical industry has continued to decline, and a variety of chemical products have experienced substantial shocks during the year. Recently, under the influence of multiple factors such as low crude oil prices and downstream maintenance, the weak cost support has led to a significant decline in chemical prices, in this context, downstream terminal products have entered the profit uptrend. According to statistics, among a variety of chemicals recently, the overall price decline of polyethylene and polypropylene products downstream of olefin is small, and the product price difference maintains stable operation; EVA prices fell slightly, product price spreads widened; Styrene prices also fell significantly. In addition, there are a number of varieties due to the impact of demand led to a decline in price, such as pure benzene due to downstream styrene, phenol ketone and other parts of the device parking…
