Claims18
A product produced by the process which comprises contacting at a temperature sufficient to cause reaction an alkenyl or alkyl succinimide containing at least one primary or secondary amine with glycidol wherein the charge mole ratio ranges from greater than 1 and up to 10 of glycidol to each of the basic nitrogens of the alkenyl or alkyl succinimide.
A product produced by the process which comprises contacting at a temperature sufficient to cause reaction glycidol with an alkenyl or alkyl succinimide of the formula ##STR6## wherein R is an alkenyl or alkyl group containing from about 10 to 300 carbon atoms;
- R.sub.1 is alkylene of 2 to 10 carbon atoms;
- R.sub.2 is hydrogen or lower alkyl;
- a is an integer from 0 to 10;
- and W is --NH.sub.2 or ##STR7## wherein R is an alkenyl or alkyl group containing from about 10 to 300 carbon atoms;
- with the proviso that if W is ##STR8## then a is not zero and at least one of R.sub.2 is hydrogen and wherein the charge mole ratio ranges from greater than 1 and up to 10 of glycidol to each of the basic nitrogens of the alkenyl or alkyl succinimide.
A product prepared by the process which comprises
- (a) contacting at a temperature sufficient to cause reaction an alkenyl or alkyl succinimide containing at least one primary or secondary amine with glycidol wherein the charge mole ratio ranges from greater than 1 and up to 10 of glycidol to each of the basic nitrogens of the alkenyl or alkyl succinimide and
- (b) reacting the adduct formed in (a) above with boric acid wherein from about 0.1 equivalents to 10 equivalents of boric acid are employed per equivalent of adduct produced in (a) above.
