Usage: It can be used as an organic solvent, reaction medium and an intermediate in organic synthesis. Its application is extremely wide.This product has a high selective extraction ability. It is used as a polymerization and condensation solvent for acrylic resins and polysulfone resins, a drawing solvent for the polymerization of polyacrylonitrile and cellulose acetate, a extraction solvent for separating alkanes and aromatics, a solvent for extracting aromatics and butadiene, a solvent for Acrylic fiber spinning,plastics,organic synthesis dyes, and pharmaceuticals in industrial processes. In the field of medicine, dimethyl sulfoxide has anti-inflammatory and analgesic effects, has strong penetration on the skin, and can dissolve certain drugs. This enables these drugs to penetrate into the human body and achieve the therapeutic purpose. Utilizing the carrier property of dimethyl sulfoxide, it can also be used as an additive for pesticides. In some pesticides, adding a small amount of dimethyl sulfoxide helps the pesticide to penetrate into plants,thereby improving the efficacy. Dimethyl sulfoxide can also be used as a dyeing solvent,de-dyeing agent,dyeing carrier for synthetic fibers,an absorption agent for recovering acetylene and sulfur dioxide,a modification agent for synthetic fibers,a coolant,an anti-freezing agent,a capacitor medium,brake fluid,a rare metal extractant,etc.
