【摘要】 采用ＧＣ和ＧＣ－ＭＳ分析了连续蒸汽法松香和滴水法松香的成分，模拟试验结果表明：聚合松香产率上的差异是由不同生产工艺松香的含水量、含油量和枞酸型树脂酸含量的不同所引起的更多还原

【Abstract】 Constituents of two rosins Produced by continuous steam distillation and direct heating processesrespectively,were analysed by GC,GC-MS. The results of simulated polymerization showed that difference inpolymerized rosin yield was due to the differences of contents of moisture,turpentune and abietic type acids ofrosins produced by different processes.更多还原
