| titleOfInvention | Process for preparing isocyanates containing alkoxysilane groups |
| abstract | The present invention relates to a process for preparing isocyanate containing alkoxysilane groups, in which, in the sequence of steps A) to D),n A) alkoxysilanoalkylamine is reacted with urea in the presence of an alcohol, optionally in the presence of at least one catalyst, to give alkoxysilanoalkylurethane, B) simultaneously or successively, if used, the catalyst is removed and/or deactivated, and low boilers, medium boilers and/or high boilers are removed, C) purified alkoxysilanoalkylurethane is thermally cleaved to release isocyanate containing alkoxysilane groups and by-product, leaving bottoms material, and D) isocyanate containing alkoxysilane groups and by-product are separated from one another and from bottoms material and collected, in which, in step C),n i) the bottoms material is wholly or partly discharged from the cleavage apparatus, ii) subjected to thermal treatment and/or purification and/or an aftertreatment in the presence of alcohol and iii) the material removed, after thermal treatment and/or purification and/or aftertreatment in step B) or C), is fed in again. |
