invention can be derived from a reading of exemplary claims 1, 16
and 25, the only independent claims on appeal. Claims 1, 16 and
25 are reproduced below.
1. A process for the preparation of polyol fatty
acid polyester, comprising heating a mixture of polyol,
fatty acid ester, emulsifying agent and catalyst under
conditions sufficient to cause reaction of the polyol
and the fatty acid ester, wherein the fatty acid chains
of the fatty acid ester have from about 6 to about 14
total carbon atoms, wherein the emulsifying agent
comprises a fatty acid soap having fatty acid chains of
from about 16 to about 22 total atoms, and wherein the
mixture is heated at a pressure sufficient to maintain
a substantially constant reflux rate of the fatty acid
ester during the reaction of the polyol and the fatty
acid ester.
16. A process for the preparation of polyol fatty
acid polyesters, comprising heating a mixture of
polyol, fatty acid ester and catalyst wherein the fatty
acid chains of the fatty acid ester have from about 6
to about 14 carbon atoms and at least 50% the polyol’s
hydroxyl groups are esterified and wherein the mixture
is heated at a pressure sufficient to maintain a
substantially constant reflux rate of the fatty acid
ester during the reaction of the polyol and the fatty
acid ester.
25. A process for the preparation of higher polyol
fatty acid polyters, comprising heating a mixture of
polyol, fatty acid ester and catalyst to form a polyol
fatty acid polyester wherein the polyol fatty acid
polyster has a pour point of not greater than about
-15°C and wherein the mixture is heated at a pressure
sufficient to maintain a substantially constant reflux
rate of the fatty acid ester during the reaction of the
polyol and the fatty acid ester.
