Methyl Sulfid Liquid Usage and Synthesis.

Methyl Sulfid Liquid is a colorless, clear and volatile liquid. It has an unpleasant odor. Methyl Sulfid Liquid is soluble in ethanol and ether and insoluble in water.

Methyl Sulfid CAS 75-18-3 is a major natural source of sulfide in the atmosphere. methyl Sulfid CAS 75-18-3 is mainly produced and released into seawater by marine organisms, and the surface seawater is highly supersaturated with dimethyl sulfide. The concentration gradient of Methyl Sulfid Raw Materials between sea and air allows for significant fluxes of dimethyl sulfide into the atmosphere, accounting for about 50% of global natural sulfur emissions, which are eventually oxidized to non-marine sulfate (NSS-SO42-), thereby affecting the natural acidity of precipitation and climate.

The concentration of Methyl Sulfid CAS 75-18-3 in seawater is generally in the range of 10-100 ng/L, which is too low to be directly analyzed. the processes of production, release and transformation of Methyl Sulfid Raw Materials are influenced by marine plankton, microorganisms and physical and chemical factors, and their mechanisms are not fully understood, together with the fact that The mechanism is not fully understood, and the easy adsorption and oxidation of dimethyl sulfide itself make the collection, preservation and determination of samples difficult.

Methyl Sulfid Liquid, is the simplest thioether compound. Its structure and properties are similar to those of dimethyl ether. It is a colorless, volatile liquid at room temperature. It has a special odor like seafood substance. In nature, it is often produced by the decomposition of proteins. It is also one of the sources of fishy seafood odor.

Methyl Sulfid Raw Materials can be used as the second step in organic synthesis, such as the ozonation reaction, for the reduction of secondary ozone 1,2,4-trioxapentacycles to completely convert olefins to aldehydes or ketones, as a solvent for polymerization reactions, and for the production of pesticides, methylthiaminic acid and dimethyl sulfoxide, as an analytical reagent, and for gas odorization and coating film removal.

Chemical Properties of Methyl Sulfid Liquid

Colorless and transparent volatile liquid. Has an unpleasant odor. Soluble in ethanol and ether, insoluble in water.

Colorless transparent volatile liquid, flammable and explosive. Highly toxic. Unpleasant odor. Soluble in ethanol and ether, insoluble in water. Relative density 0.845. melting point - 83℃. Distillation range 36-39℃, refractive index 1. 4438. boiling point 37.5℃. Self-ignition point 206.1℃, flash point - 17.8℃, flammable range 2.2% to 19.7% in air.

This product is toxic. Low concentration of dimethyl sulfide vapor generally causes nausea, loss of appetite, and high concentration of vapor has a paralyzing effect on the central nervous system. The production process should be airtight to prevent running, venting, dripping and leakage. The production site should be ventilated and the operator should wear protective gear. In case of poisoning, move to fresh air in time and ask a doctor for treatment.

Methyl Sulfid Liquid Use stainless steel pressure-resistant barrel for packing. Keep away from heat source, fireproof and explosion-proof in storage and transportation. Store and transport according to the regulations of flammable and toxic chemicals.

Production method of Methyl Sulfid Liquid

Methyl Sulfid Liquid has dimethyl sulfate method, carbon disulfide method, hydrogen sulfide method and paper black liquor method according to the different raw materials used.

1. Dimethyl sulfate method Dimethyl sulfate and sodium sulfide at 80-90 ℃ reaction to produce dimethyl sulfide.
2. Carbon disulfide method Methanol and carbon disulfide reaction at 300 ℃, aluminum hydroxide catalyst to produce dimethyl sulfide.
3.  Hydrogen sulfide method Methanol is dehydrated at high temperature with activated alumina as catalyst to produce dimethyl ether; dimethyl ether then reacts with hydrogen sulfide under the action of catalyst to produce dimethyl sulfide.
4. Paper black liquor method in the pulp cooking process, about 62% of the non-fiber dissolved in the cooking liquid, this pulp waste is commonly known as "black liquor" which contains a large amount of lignin. The black liquor is reacted with sulfur or sodium sulfide at high temperature and pressure, so that the lignin's methoxy dehiscence is combined with sulfur ions to produce dimethyl sulfide.

Methanol and carbon disulfide synthesis method Mix methanol and carbon disulfide according to the theoretical ratio, measure, heat, and send into the reactor for reaction, the reaction gas is condensed and refined to the finished product.

Methanol and hydrogen sulfide synthesis method Methanol and hydrogen sulfide are mixed in a certain ratio, preheated and fed into the catalytic reactor for reaction, and the reactants are separated and de-watered, and then refined to the finished product.

Dimethyl sulfate and sodium sulfide synthesis method

1. Methyl Sulfid Raw Materials is obtained by the reaction of potassium sulfide and chloromethane in methanol solution.
2. Methyl Sulfid CAS 75-18-3 is obtained by heating methanol with carbon disulfide or hydrogen sulfide and reacting in the gas phase.
