PEMANFAATAN MINYAK BIJI RAMI (LINSEED OIL) DAN GLISEROL BY-PRODUCT BIODIESEL UNTUK PEMBUATAN VERNIS ALAMI

摘要: Abstract Varnish is coating material that produced by using polymer. Actually  natural varnish manufacturing polymer like gondorukem. The research to study about optimizing of  reactant composition as the ratio of OH/COOH and operation temperature in process making from gondorukem, linseed oil glycerol by-product biodiesel alcoholysis method. reaction done reactor agitator. consists two steps, 1). forming monoglyceride, 2). varnish. Both steps at same (200 o C, 220 240 C 260 C). Reactant used equivalent OH/COOH: 1,1; 1,2; 1,3. We analyze free concentration first step and  acid value second reaction. best result obtained 1,2 C. Key word : varnish, alcoholysis, OH/COOH, oil, biodiesel.
