ジメチルスルホキシド

ジメチルスルホキシド（DMSO）は、無色透明で吸湿性の液体であり、わずかにニンニク様の臭気を有し、沸点が高く（189 ℃）；水およびほとんどの有機溶媒と混和する。これは極性非プロトン性有機硫黄化合物に分類される。ジメチルスルホキシドは、主に化学合成、医薬品製剤および高分子加工における高性能溶媒として用いられ、またバイオテクノロジー分野では反応媒体および低温保存剤として機能する。その主要な産業用途には、農薬合成、医薬品原体（API）の製造、電子材料加工および特殊コーティングにおける溶媒としての役割が含まれる。さらに、ポリアクリロニトリル繊維の製造や、膜形成プロセスにおける加工補助剤としても使用される。

1. It can be used for the extraction of arene, also as the reaction medium used for resins and dyes, and applied to acrylic polymerization and spinning solvent. 2. It can be used as an organic solvent, reaction medium and the intermediates of organic synthesis. It is highly versatile. This product has a highly selective extraction capacity, and can be used as the polymerization and condensation solvent of acrylic resin and polysulfone resin, as the polymerization and spinning solvent of polyacrylonitrile and cellulose acetate, as the extraction solvent for separating alkanes and arenes, and as the reaction medium for the arenes, butadiene extraction, acrylic fiber, plastic solvents, organic and synthetic dyes, and pharmaceuticals industries. In the field of medicine, dimethyl sulfoxide has anti-inflammatory and analgesic effect with a strong capability of penetration through the skin, and thus being able to dissolve certain drugs and boost their penetration into the human body to achieve the therapeutic purposes. Taking this carrier property of dimethyl sulfoxide can make it be used as pesticide additives. Add a small amount of dimethyl sulfoxide in some pesticides can facilitate the penetration of pesticides into the plant in order to improve the efficacy. dimethyl sulfoxide can also be used as the dye solvent, dye removing agent, and dye carrier for the synthetic fibers. It can also be used as the absorbent of recycling acetylene and sulfur dioxide and also the modifiers of synthetic fiber, antifreeze agent and the capacitor dielectric, brake oil, and extractant of the rare metals. 3. It can be used as analytic solvents and fixing agent of gas chromatography as well as the solvent for analyzing UV spectra.
