ALKOXYLATION PROCESSES USING MONOCATIONIC AND DICATIONIC CYCLOPENTADIENYL PHOSPHORUS CATALYSTS
Alkoxylations are performed by reacting a cyclic oxide with a starter in the presence of certain cyclopentadienyl phosphorus catalysts. The cyclopentadienyl phosphorus catalysts are highly active and effective in such small quantities that it is often unnecessary to remove catalyst residues from the...

description | Alkoxylations are performed by reacting a cyclic oxide with a starter in the presence of certain cyclopentadienyl phosphorus catalysts. The cyclopentadienyl phosphorus catalysts are highly active and effective in such small quantities that it is often unnecessary to remove catalyst residues from the product. The cyclopentadienyl phosphorus catalysts are very effective in alkoxylating even low molecular weight starters such as glycerol and sorbitol.
L'invention concerne des alcoxylations qui sont effectuées par mise en réaction d'un oxyde cyclique avec un amorceur en présence de certains catalyseurs de cyclopentadienyle phosphore. Les catalyseurs de cyclopentadienyle phosphore sont hautement actifs et efficaces dans de telles petites quantités qu'il n'est souvent pas nécessaire d'éliminer les résidus de catalyseur du produit. Les catalyseurs de cyclopentadienyle phosphore sont très efficaces dans l'alcoxylation même d'amorceurs de faible poids moléculaire tels que le glycérol et le sorbitol. |
