Abstract

Polyol compounds obtained by epoxidation dan hydroxylation, the results obtained with the reaction yield of 69.23%. Potassium soap mixture in the form of a polyol obtained by saponification polyol with Potassium Hydroxide with a yield of 70.36%. Polyol and potassium soap in the form of a polyol mixture was analyzed by FT-IR spectrophotometer.Respectively iodine from moringa seed oil and polyol are 107.3769 mg I / gram of oil and 4.6755 mg I / gram of oil. HLB of fatty acid potassium soap of moringa seed oil and potassium soap in the form of a mixture of polyol is determined by titration method and obtained HLB of fatty acid potassium soap of moringa seed oil amounted to 5,2178 while the potassium soap in the form of a polyol mixture of 8,4767. Free alkalinity of soap potassium mixture in the form of a polyol is 0.551%. Based on the stability and strength of the foam test, the concentration of potassium soap mixture in the form polyols having the most excellent foam stability is 1% and which has the best strength is 1%.Keywords: moringa seed oil, epoxidation, polyol, saponification

Abstract

Determination degree of esterification with the baseline on the synthesis method aldimine chitosan acetate by esterification of aldimine chitosan with acetic anhydride has done. In this research, chitosan modified by chemical being aldimine chitosan acetate. Synthesis aldimine chitosan acetate produced by the esterification reaction between aldimine chitosan with acetic anhydride. The result of FT-IR analysis of aldimine chitosan acetate showed in wavenumbers 3448.72 cm-1, which indicated stretching vibration hydroxyl group -OH. Vibration absorption wave numbers 1735.93 cm-1 indicated carbonyl group C = O, ester and backed group C-O-C with wavenumbers 1033.85 cm-1. vibration absorption in wavenumbers 1651.07 cm-1 indicated the presence of C = N. Degree of esterification or degree of acetylation (DA) in aldimine chitosan acetate assign value 82.85%.
