摘要:
Organosilicon compounds having the formula I and/or II wherein R1 is a mixture and the proportion of one component of the mixture is 10 to 50 mol %, are produced by reacting silanes having the formula III with mixtures of alcohols having the general formula R1—OH, with elimination of R—OH, and R—OH is continuously separated off from the reaction mixture by distillation. The organosilicon compounds can be used in rubber compounds.
摘要:
A composition containing organosilicon compounds having the formula I and/or II wherein R is ethyl, R1 is a mixture such that the proportion of one component of the mixture is 10 to 50 mol % and is the same or different C9-C30 branched or unbranched monovalent alkyl, and R2 is a branched or unbranched, saturated or unsaturated, aliphatic, aromatic or mixed aliphatic/aromatic divalent C1-C30 hydrocarbon is produced by reacting silanes having the formula III with mixtures of alcohols having the general formula R1—OH, with elimination of R—OH, and R—OH is continuously separated off from the reaction mixture by distillation. The organosilicon compounds can be used in rubber compounds.
摘要:
Organosilicon compounds of the general formula I and/or II are produced by reacting silanes of the general formula III with alcohols of the general formula R′—OH, with elimination of R—OH, wherein R—OH may be continuously separated from the reaction mixture by distillation. The organosilicon compounds may be used in rubber mixtures. Compounds, such as rubbers, produced using such organosilicon compounds.
