摘要
以汽油-硫酸法生产聚合松香的方法和工艺对马尾松、洪都拉斯加勒比松、云南松/思茅松、湿地松、南亚松的松香进行聚合松香聚合性能试验.结果表明,洪都拉斯加勒比松松香与马尾松松香具有同样好的聚合性能,云南松/思茅松较马尾松松香得率稍低,湿地松、南亚松松香不适合于生产聚合松香.
Abstract
By adopting gasoline-sulfuric acid method in production of polymerized rosin, we tested and compared the performance in polymerization of rosin from Pinus massoniana, P. Caribaea var. Hondurensis, P. Yun-nanensis/P. Kesiya var. Langbianensis, P. Elliottii, and P. Latteri. The results showed that P. Massoniana and P. Caribaea var. Hondurensis performed best in producing polymerized rosin, followed by P. Yunnanensis/P. Kesiya var. Langbianensis, P. Elliottii, and P. Latteri were worst, not suitable for production of polymerized rosin.
