TOXIC; inhalation, ingestion or contact (skin, eyes) with vapors, dusts or substance may cause severe injury, burns or death. Contact with molten substance may cause severe burns to skin and eyes. Reaction with water or moist air will release toxic, corrosive or flammable gases. Reaction with...
When methanesulfonyl chloride was used instead of the anhydride for the elimination of water from 11.8, the benzylic chloride was isolated in 25% yield. The chloride did not undergo elimination under the reaction conditions. View article Discovery and optimization of novel pyrazole-benzimidazole CPL...
At present, in China, sulfur vein is basically used as a raw material, and methylsulfonyl chloride is produced by a process route after methylation with dimethyl sulfate and reaction with chlorine gas. The total yield of the reaction is only about 65%. The product needs to be distilled ...
CONSTITUTION:Methanesulfonyl fluoride is produced by reacting methanesulfonyl chloride with a fluoride in the presence of water at 0-120 deg.C. The reaction product is separated only by liquid separation process without using filtration, distillation, etc. Methanesulfonyl chloride used as the raw ...
The heats of formation of liquid methanesulfonyl chloride, -126.91 ± 1.54, and methyl methanesulfonate, -164.34 ± 1.58, were determined by measuring the heats of reaction of methanesulfonyl chloride with water or methanol in the presence of a suitable basic catalyst. Heats of vaporization (based ...
This reaction needs reagent benzene and dibenzoyl peroxide. When you are using this chemical, please be cautious about it as the following: (1)Causes burns; (2)Irritating to eyes and respiratory system; (3)In case of contact with eyes, rinse immediately with plenty of water and seek medical...
the reaction finishing point is reached, then, the temperature is lowered to the room temperature, cold water is added into reaction mixtures, solids in a system are completely dissolved, the still standing delamination is carried out, an upper water layer is abandoned, oil phases at the lower...
There is provided a method for producing trifluoromethanesulfonyl fluoride (CF 3 SO 2 F) by reaction of trifluoromethanesulfonyl chloride (CF 3 SO 2 Cl) with a metal fluoride in the presence of water, wherein the amount of the water is in the range of 0.6 mass% to 10.0 mass% based ...
O-aminodiphenyl ether and methanesulfonyl chloride are used as raw materials to react in an N,N-dimethylaniline solvent under heating conditions, the reaction liquid precipitates in highly acidic water in an ice water bath, and the precipitate is washed with water. The method comprises the ...
