Abstract: An energy-conserving method for the manufacture of polyaminoamides is described which involves the reaction of a polycarboxylate ester with a mono and/or polyalkylene polyamine in the presence of 0 to about 5% by weight water by heating approximately stoichiometric proportions of the two reactants to the temperature at which the amidification reaction becomes self-sustaining, then utilizing the exothermic heat of reaction to sustain the reaction at a desired temperature. During the reaction, the heat of reaction is used to vaporize an alcohol reaction product and remove the alcohol from the reaction vessel and from further contact with the reaction vessel contents.

Abstract: Diphenyl phthalates are purified by crystallizing them from dipolar-aprotic solvents or solutions of solvents containing such solvents. The phthalate solutions are advantageously, but not necessarily, treated in a carbon column in hydrocarbon solvent without dipolar-aprotic solvents present to remove part of the color and impurities, and then dipolar-aprotic solvents are added to the solution before crystallization to aid in the final removal of color and impurities.
