ã€Abstractã€‘ Masson pine resin(Tall oil) was methlylated by tetramethylammonium hydroxide(TMAH) and the pro_ ducts were analyzed by GC-MS. The results indicated that GC-MS analysis after methylation of resin by TMAH was a fast and effective method for the determination of acidic components of resin. Since the methylation of unsaturated fatty acids in resin was more difficult than that of resin acids, methylation time should be properly prolonged for the completion of methylation.æ›´å¤š è¿˜åŽŸ
