The uses of dimethyl sulfoxide are as follows:
Industrial applications
1. Organic synthesis and processing
As a solvent and reaction medium for acrylonitrile polymerization and polyurethane synthesis. Used for the synthesis of high-performance materials such as polyamide, polyimide, and polysulfone resin. As an absorbent and dyeing solvent for gases such as aromatics and butadiene.
2. Surface treatment and chemical engineering
Metal processing, printing, and coating stripping (such as epoxy resin removal). Dye dissolution and stability improvement, increasing dye yield.
3. Special solvents
Dissolve transition metal halides such as chromium chloride and manganese chloride. Rust inhibitor solvent and microbial inhibitor.
Pharmaceutical field
1. Pharmaceutical preparations
Enhance transdermal absorption of drugs (such as eye drops, creams). As a carrier and stabilizer for anticancer drugs and antibiotics.
2. Therapeutic effect
Anti inflammation, pain relief, and improvement of kidney function (such as clearing oxygen free radicals and dissolving amyloid protein). Promote blood circulation and wound repair.
Scientific research field
1. Biochemical research
Separation and purification solvents for proteins and nucleic acids. Cell cryopreservation protection (reducing ice crystal damage).
2. Analytical techniques
Solvent or ion pair pipettes for instruments such as gas chromatography and mass spectrometry.
Agriculture and Environmental Protection
1. Increase pesticide efficiency
Improve pesticide permeability and enhance insecticidal effect.
2. Plant regulation
Promote plant growth (by dispersing water containing DMSO).
Other applications
1. Precision mechanical cleaning: Clean electronic components using low toxicity and low-temperature dissolution characteristics.
2. Film manufacturing: used for the production of separation membranes such as artificial kidney fibers and ion exchange membranes.
