摘要： The invention relates to a method for producing alkanesulfonic acids from dialkyl sulfites, which comprises the following steps: transformation of dialkyl sulfite in the presence of a suitable catalyst in to the corresponding alkanesulfonic acid alkyl ester; and hydrolysis of said alkanesulfonic acid alkyl ester to obtain the corresponding alkanesulfonic acid.

摘要： The invention relates to a method for producing trialkoxysilanes by reacting silicon metal with an alcohol on a catalyst containing copper, in an inert reaction medium containing diphenylalkanes. The invention also relates to the use of diphenylalkanes as an inert reaction medium for reacting silicon metal with an alcohol on a catalyst containing copper.

摘要： The invention relates to a method for producing phosphorous-nitrogen compounds by reacting phosphorous sulfides with an amino component, which has at least one nitrogen atom with at least two hydrogen atoms or has at least two nitrogen atoms with at least one hydrogen atom. According to the invention, the desired phosphorous-nitrogen compounds are formed a temperature Tmax of ≥ 200 °C. These compounds are preferably used as flameproofing agents in thermoplastic molding materials which, among other things and in addition to a thermoplastic polymer, can still contain a nitrogen compound, fillers, lubricants, common additives and/or common viscosity modifiers.
