性质描述: 微黄至黄红色透明、硬脆、不松脂气味的玻璃状固体。软化点≥72-74℃,沸点约300℃(0.67kPa)。易溶于乙醇、乙醚、丙酮、丙、二氯乙烷、二硫化碳、松节油、石油醚、汽油;溶于油类和碱溶液,不溶于水。桦香是各种松香酸异构体的混合物。
生产方法: 脂松香直接用采自活松树的含油生松脂作原料,进行水蒸气蒸馏脱去松节油而得,这是我国目前生产松香的主要方法。浮油松香以亚硫酸盐法木浆所产生废液表面上的粗浮油作原料,经洗涤、酸解、油水分离、干燥脱水、预热、真空分馏等工序而得。木松香以松树桩、松根明子、松木碎片等为原料,经破碎、筛选、再用汽油等溶剂萃取、浸提、沉淀、脱色、蒸发回收溶剂,分馏而得产品。
用途: 广泛用于肥皂、造纸、油漆、油墨、橡胶、火柴、塑料、制药、印染、机电等工业部门。日本的用途分配(1977年统计):造纸上胶剂 37% 涂料  8%合成橡胶乳化剂 25% 粘合剂  8%印刷油墨 13% 地板砖胶 6%
