Abstract:
1. A process for making a compound having the formula (I): wherein R 1 is a C 1 to C 4 hydrocarbon, linear or branched, and mixtures thereof, R 2 is C 7 to C 22 linear or branched hydrocarbon and mixtures thereof, and the index of x is greater than or equal to 3; the process comprising the steps of: (A) ethoxylating the compound of R (B) conducting Step (A) in the presence of a base; (C) reacting the product of Step (B) with a compound having the formula (III):  wherein R (D) conducting Step (C) in the presence of a base catalyst; (E) applying heat to Steps (C) and (D) ranging in temperature of from about 60° C. to about 200° C.; and (F) optionally, conducting Steps (C) and (D) in a vacuum ranging from about 20 kPa to about 0.013 kPa (200 mm Hg to 0.1 mm Hg) for a period of time ranging from 0.1 to 10 hours.
