PROCESS FOR THE INTERCONVERSION OF CRYSTALLINE FORMS OF ETHYLENE BIS-STEARAMIDE ABSTRACT OF THE DISCLOSURE A process for preparing alpha and beta crystalline forms of N,N'-ethylene bis-stearamide (EBS). Heating of EBS at temperatures of 120°-160°C to melt the EBS results in formation of 95+%; alpha which when cooled to 40°C or less remains in the alpha state, but upon reheating to about 80°C results in 95+% conversion to the beta crystalline form. Heating of the alpha crystalline form at temperatures ranging from about 45-90°C for selected periods of time results in mixtures of alpha and beta.
