Dimethyl Sulfone Powder Usage and Synthesis.

Dimethyl sulfone is the main substance of the human body to maintain the balance of biological sulfur elements, with therapeutic value and health care functions for human diseases, it is an essential drug for human survival and health protection, foreign countries will be used as a large number of vitamins and vitamins as important as nutritional supplements, China's research on the application of dimethyl sulfone has not yet been well carried out, so that all the products are used for export at present.

Uses of Dimethyl Sulfone.

1, can eliminate viruses, strengthen blood circulation, soften tissues, relieve pain, strengthen the muscles and bones, calm the spirit, enhance physical strength, maintain the skin, hair beauty, treatment of arthritis, mouth ulcers, asthma, constipation, infusion of blood vessels, remove toxins in the stomach and intestines.

2, Dimethyl sulfone can be used as food and feed additives for humans, pets and livestock organic sulfur nutrient supplementation.

3, when used externally, it can make the skin smooth, muscle suppleness, and can reduce pigmentation, recently as a cosmetic additive dosage increased dramatically.

4, In medicine, it has good analgesic, promote wound healing and other functions.

5, Excellent penetrating agent in the production of drugs.

Preparation method of Dimethyl Sulfone.

1. Oxidation under ultraviolet irradiation passes oxygen through ultraviolet irradiation into a solution of dimethyl sulfoxide, which undergoes an oxidation reaction under ultraviolet irradiation, resulting in dimethyl sulfoxide, which is frozen with ice brine to cause crystals to precipitate out.

Separation. Recrystallized when needed. This oxidation process is also natural dimethyl sulfur to generate dimethyl sulfoxide and dimethyl sulfone process.

2. Oxidation of nitrogen oxidation of dimethyl sulfoxide into the reactor, heated to 140 ~ 146 ℃, through the nitrogen dioxide oxidation.

After the reaction with ice brine cooling, Chemicalbook crystallized dimethyl sulfoxide, filtered to get white needle-like crystalline crude. After the reaction with ice brine cooling, crystallization of dimethyl sulfoxide, filtration of white needle-like crystalline crude. Distillation to collect 138 ~ 145 ℃ (740mmHg) fraction for the finished product.

3. Hydrogen peroxide oxidation reaction kettle into the dimethyl sulfoxide, heated to 90 ~ 100 ℃, drop 27.5% hydrogen peroxide, reflux reaction, drop hydrogen peroxide, continue to react for several hours. Filtering, cooling with ice brine so that dimethyl sulfoxide crystals precipitated, centrifugal separation, crystals washed with 95% ethanol or recrystallization of fine products. Drying. The mother liquor is concentrated and recovered by crystallization. Total yield 90%~92%.

Product Method of Bulk Dimethyl Sulfone Powder.

Obtained from dimethyl sulfoxide by nitric acid oxidation. Dimethyl sulfoxide was oxidized by nitric acid at 140-145°C. After the reaction, it was cooled down and filtered to obtain the crude product with white needle-like crystals. Then distill under reduced pressure, collect 138-145 ℃ (98.42kPa) fraction is the finished product.
