Abstract
A modified natural oil made from reacting at least one natural oil or fat comprising at least one ene moiety with at least one of an enophile or dienophile mixture to form at least one modified natural oil, and reacting the at least one modified natural oil which may be used in a variety of processes.
Claims24
A method for producing a polyol, comprising:
- providing at least one natural oil or fat comprising at least one ene moiety;
- reacting the at least one natural oil or fat with at least one of an enophile or enophile/dienophile mixture in a substantial absence of a double bond isomerization catalyst to form at least one modified natural oil;
- reacting the at least one modified natural oil with at least one alkylene oxide in the presence of at least one double metal cyanide catalyst to form at least one alkoxylated modified natural oil polyol.
(canceled)
An alkoxylated modified natural oil polyol comprising a reaction product of at least one alkylene oxide and at least one modified natural oil, wherein:
- the at least one alkylene oxide and the at least one modified natural oil are reacted in the presence of a double metal cyanide catalyst;
- the at least one modified natural oil comprises a reaction product of at least one natural oil or fat and at least one of an enophile or enophile/dienophile mixture in a substantial absence of a double bond isomerization catalyst, and wherein the at least one natural oil or fat comprises at least one ene moiety.
An alkoxylated modified natural oil polyol comprising a reaction product of at least one alkylene oxide and at least one ring opened modified natural oil, wherein:
- the at least one alkylene oxide and the at least one ring opened modified natural oil are reacted in the presence of a double metal cyanide catalyst;
- the at least one ring opened modified natural oil comprises a reaction product of at least one ring opener and at least one modified natural oil;
- and
- the at least one modified natural oil comprises a reaction product of at least one natural oil or fat and at least one of an enophile or enophile/dienophile mixture in a substantial absence of a double bond isomerization catalyst, and wherein the at least one natural oil or fat comprises at least one ene moiety.
