Title:
PRODUCTION OF UNSATURATED ALCOHOL
Document Type and Number:
Japanese Patent JP3693705
Kind Code:
B2
Abstract:
PURPOSE: To obtain an unsaturated alcohol which is a hydrated even number oligomer of a conjugated alkadiene useful as a raw material for cosmetics, etc., in high yield and selectivity by reacting the alkadiene with water in the presence of carbon dioxide using a pd compound and a specific phosphorus compound as catalysts.
CONSTITUTION: This method for producing (E) an unsaturated alcohol having a skeleton obtained by polymerization of a conjugated alkadiene (e.g. 6- vinyl-2,8,13-tetradecatrien-1-ol) is to react (C) a conjugated alkadiene with (D) water in the presence of (B) carbon dioxide using (A) a pd compound and a phosphorus compound having one or more trivalent phosphorus-oxygen single bonds [e.g. a compound of formula I [A1 is a (substituted)aryl or a (substituted) alkyl; A2 and A3 are each a (substituted)arylene; Q is O, S, CO, etc.; (x) and (y) are each 0 or1] or a compound of formula II[A4 is A1; A5 and A6 are each a (substituted)aryl] as catalysts.
