Nitric acid and negative water are heated carefully to 80-88 °C with fractional addition of methyl thiocyanate and the temperature being automatically rose to about 105 ℃. After the reaction becomes mild, the reaction was heated to 120 ° C and reacted for 5 hours to obtain a crude ...
an obtained reaction solution is subjected to water removing in vacuum, and is subjected to reduced pressure distillation for 3 to 5h under a pressure of 0.6 to 0.8MPa so as to obtain methanesulfonic acid finished products; and residual solution obtained via distillation is send back to the cir...
Infrared Studies of the Reaction of Methanesulfonic Acid with Trimethylamine on Surfaces Both of these acids formed initially in the gas phase react with ammonia and amines in air to form and grow new particles, which is important for ... N Nishino,KD Arquero,ML Dawson,... - 《Environmental...
Methanesulfonic acid, also known as CH3SO3H, is the simplest alkylsulfonic acid. It is a colorless liquid that is soluble in water and slightly soluble in organic solvents. With a strong acidity and a pKa of approximately -0.6, it does not undergo hydrolysis in hot water or alkaline solutions...
(fuming sulfuric acid, H2SO4saturated with SO3), in the presence of a sulfonyl peroxide initiator. Methane can originate from natural gas or biogas. The reaction occurs at moderate temperatures (~ 50 °C) and pressures (~ 100 bar). No expensive metal-containing catalyst is required. ...
Methane sulfonic acid (MSA) is an oxidation product of the reaction of OH radical with dimethyl sulfide and, hence, should be an important constituent of m... ES Saltzman,DL Savoie,RG Zika,... - 《Journal of Geophysical Research Oceans》 被引量: 374发表: 1983年 Coherence between seasonal...
The mesylate salt is obtained by reaction with methanesulfonic acid. Anna M. Wodlinger, Remington: The Science and Practice of Pharmacy, 2005Word History First Known Use 1892, in the meaning defined above Time Traveler The first known use of methanesulfonic acid was in 1892 See more words ...
We report here diffuse reflectance infrared Fourier transform spectrometry (DRIFTS) studies of the reaction of MSA with trimethylamine (TMA) on a silicon powder at atmospheric pressure in synthetic air and at room temperature, either in the absence or in the presence of water vapor. In both ...
A faster reaction was observed in toluene than in chlorinated solvents, which was thought to result from a slightly tighter interaction between the acid catalyst and the monomer in a less polar solvent. With both acids, the experimental Mn values varied linearly with the monomer-to-initiator ...
In order to synthesize telechelic poly(tetrahydrofuran) [poly(THF)] with benzoic acid terminal groups (9), the reaction of bifunctional living cationic poly(THF) initiated by trifluoromethanesulfonic anhydride with lithium or sodium salt of methyl p-hydroxybenzoate was performed in THF solvent at 0...
