| titleOfInvention | Process for the production of isocyanates containing alkoxysilane groups |
| abstract | Process for the production of isocyanate containing alkoxysilane groups, in which, in the sequence of steps A) to D), A) alkoxysilanoalkylamine is reacted with urea in the presence of an alcohol, optionally in the presence of at least one catalyst, to give alkoxysilanealkylurethane, B) simultaneously or successively - if the catalyst is used, separated and / or deactivated, as well as - low boiling point products, medium boiling point products and / or high boiling point products are removed , C) purified alkoxysilanealkylurethane is thermally dissociated under liberation of isocyanate containing alkoxysilane groups and with low permanence of tail material, and D) isocyanate containing alkoxysilane groups and secondary product is separated from each other and from the tail material, and collected, characterized because, in which, in step C) i) the glue material is completely or partially removed from the dissociation apparatus, ii) it is heat treated and / or pur ifica and / or subjected to a post-treatment in the presence of alcohol, and iii) the extracted material is fed back to step B) or C) after heat treatment and / or purification and / or post-treatment. |
