Product Description

 99% min cas 75-75-2 Methanesulfonic acid 


Methyl thiocyanate from nitric acid derived. The nitric acid and negative water carefully heated to 80-88 ° C, add methyl thiocyanate sub-divided, the temperature automatically rose to about 105 ℃. After the reaction is moderated, heated to 120 ° C, the reaction for 5 hours to give the crude product. The crude product diluted with exchange water, add 25% barium hydroxide solution was adjusted to pH 8-9, filtered. The filtrate was reduced to crystallization, the crystallization washed with methanol to nitrate, barium methanesulfonate. Then base to join the exchange boiling water, hot and sulfuric acid decomposition, filtration, the filtrate was concentrated under reduced pressure to the water so far, that is the finished product. Another manufacturing method is methyl isothiourea sulfate by chlorination, oxidation, hydrolysis derived. The methyl isothiourea sulfate added to the water, at 20-25 ℃ into the chlorine, the solution color to yellow, and the bottom of the bottle there, the temperature dropped, the exhaust pipe has a lot of residual chlorine emissions and other phenomena, the reaction end. The reaction solution was extracted with chloroform, and the extract was dried and distilled at 60-62 ° C under normal pressure to remove chloroform. Then the mixture was distilled under reduced pressure to collect methyl sulfonyl chloride at 60-65 ° C (2.67 kPa). The base is added dropwise with stirring hot water at 80 ℃, heat hydrolysis about 2h, until the reaction liquid drops disappear so far. The reaction solution was concentrated under reduced pressure to a syrup, diluted with water, and then concentrated under reduced pressure until no water was distilled off to obtain methanesulfonic acid.

Product expansion

1> Cosmetic Raw Materials: Cosmetics is a variety of raw materials through a reasonable deployment of processing from the compound mixture. Cosmetics with a wide range of raw materials, different performance. According to the raw material properties and uses of cosmetics, can be divided into matrix materials and auxiliary raw materials in two categories. The former is a class of cosmetics in the main raw materials, cosmetics in the possession of a large proportion of the cosmetics play a major role in the role of the material. The latter is the formation of cosmetics, stability or to give color, smell and other characteristics of the role of these substances in the cosmetic formula is not used, but it is extremely important. Cosmetics are natural, synthetic or extracted from the role of different substances as raw materials, by heating, mixing and emulsification and other production processes processed from the chemical mixture.

2> Active Pharmaceutical Ingredients(API): API refers to the raw materials in the production of various types of preparations, which is the active ingredient in powder,crystal and paste for medicine use through chemical synthesis,plant extract, and preparations of biotechnology institute.It is one substance or mixture during the medicine making period, it can not be taken directly by patients.

3> Fragrance And Spices: Spice is a substance that can be scented by smelling or scented by taste, and is the raw material for the preparation of the fragrance. Spices are an important part of fine chemicals, it is composed of natural spices, synthetic spices and single fragrance.

4> Organic Raw Material: Intermediates are also known as organic intermediates. The use of coal tar or petroleum products as raw materials to produce dyes, pesticides, pharmaceuticals, resins, additives, and other intermediates.

5> Chemicals Used In Paints: Paint, the traditional Chinese name is paint. So-called coating is coated on the surface of the object that be protected or be adornment, and with the continuous film coating to form strong adhesion, usually in resin, or oil, or emulsion is given priority to, add or not add pigment, filler, add the corresponding additives, organic solvents or water preparation of viscous liquid.
