| 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, n B) simultaneously or successively, if used, the catalyst is removed and/or deactivated, and low boilers, medium boilers and/or high boilers are removed, n C) purified alkoxysilanoalkylurethane is thermally cleaved to release isocyanate containing alkoxysilane groups and by-product, leaving bottoms material, and n D) isocyanate containing alkoxysilane groups and by-product are separated from one another and from bottoms material and collected, n 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. |
