Abstract

Abstract Described are ether carbinols defined according to the generic structure: <IMAGE> wherein X1 represents a moiety selected from the group consisting of: <IMAGE> +TR <IMAGE> and wherein Y1 represents C4 or C5 alkylene or C4 or C5 alkenylene or C4 or C5 alkynylene; processes for preparing such ether carbinols by means of first reacting allyl ethers with a mixture of carbon monoxide and hydrogen by means of an oxoreaction to produce ether carboxaldehydes and then reducing the thus formed ether carboxaldehydes to ether carbinols; or reacting camphene with appropriate diols; as well as methods for augmenting or enhancing the aroma or taste of consumable materials including perfumes, colognes and perfumed articles; foodstuffs, chewing gums, chewing tobaccos, medicinal products and toothpastes; and smoking tobaccos and smoking tobacco articles by adding thereto an aroma or taste augmenting or enhancing quantity of the thus produced ether carbinols. Also described are two ether carboxaldehydes having one of the structures: <IMAGE> +TR <IMAGE> processes for preparing such ether carboxaldehydes by means of reacting out an appropriate allyl ether with a mixture of carbon monoxide and hydrogen by means of an oxo-reaction as well as methods for augmenting or enhancing the aroma or taste of consumable materials including perfumes, colognes and perfumed articles; foodstuffs, chewing gums, chewing tobaccos, medicinal products and toothpastes; smoking tobaccos and smoking tobacco articles by adding thereto an aroma or taste augmenting or enhancing quantity of the thus produced ether carboxaldehydes.

Claim 5
Dependent Claim 173 words
A process for producing a compound defined according to the genus: ##STR194## wherein Y 1 is a moiety selected from the group consisting of: C 4 -C 5 alkylene; C 4 -C 5 alkenylene; and C 4 -C 5 alkynylene comprising the step of adding to camphene defined according to the structure: ##STR195## a diol defined according to the structure: ##STR196## thereby effecting the reaction: ##STR197## wherein Y 1 represents C 4 -C 5 alkylene, C 4 -C 5 alkenylene or C 4 -C 5 alkynylene; the reaction taking place in the presence of a Lewis acid catalyst at a temperature of from about 60° C. up to about 100° C. at a pressure in the range of from about 1 atmosphere up to about 10 atmospheres; the time of reaction varying from about 2 hours up to about 20 hours; the mole ratio of diol having the structure: ##STR198## to camphene varying from about 1:2 up to about 3:1 and then recovering the compound having the structure: ##STR199## from the reaction mass.
