The present invention provides an electroless process for making a catalyst in a liquid or gaseous medium comprising contacting a base metal with a chemical cleaning agent and simultaneously or sequentially treating said base metal under reducing conditions with a noble metal-containing material, the catalyst prepared using the process, and a method of using the catalyst.

Noble metal supported on a base metal catalyst

Compositions containing an acryloxysilane or a methacryloxysilane and an N,N-dialkylaminomethylene phenol in an amount at least sufficient to inhibit polymerization of the silane during its formation, purification and storage. Methods for producing such compositions are also provided.

Inhibited acryloxysilanes and methacryloxysilanes

An extractive distillation process for recovering trimethoxysilane from a trimethoxysilane-methanol mixture is provided using as the extractive solvent tetramethoxysilane.

Process for recovering trimethoxysilane from a trimethoxysilane and

This application relates to certain novel hydroxybicyclosiloxanes that are particularly useful as foam stabilizers for rigid polyurethane foams. The novel hydroxybicyclosiloxanes have critical siloxane molecular weights and are produced by an addition reaction involving hydrosiloxanes and olefinically unsaturated bicyclic alcohols that contain an olefinic bond which does not shift significantly during the reaction.

Hydroxybicyclosiloxane rigid urethane foam stabilizers

This application relates to certain novel hydroxyalkenylsiloxanes that are particularly useful as foam stabilizers for rigid polyurethane foams. The novel hydroxyalkenylsiloxanes have critical siloxane molecular weights and are produced by an addition reaction involving hydrosiloxanes and acetylenically unsaturated alcohols that contain a terminal acetylenic bond which does not shift significantly during the reaction.
