松香松香rosin松树的含油树脂经加工除去松节油后的热熔物。常温下为固体，主要成分为树脂酸，外观随原料和加工方法而异，通常呈淡黄至黄红色，有时呈暗红色至近黑色。性硬脆，易碎裂，断面有光泽。松香具有防潮、绝缘、乳化、粘合、防腐等作用，广泛用于造纸、医药、橡胶、电缆胶粘制、肥皂、口香糖等工业部门。1995年中国产40多万吨，占世界总产量的1/3，出口20多万吨，占世界总贸易的一半，年创汇1亿多美元。松香按原料来源分脂松香、木松香（或称浸提松香）和浮油松香；按加工深度分为天然松香、改性松香和松香衍生物。松香中的树脂酸约占90％，其余均为脂肪酸和不皂化物。松香溶于乙醇、乙醚、丙酮、苯和松节油等，不溶于水。密度1.070～1.085克/厘米3，软化点68～82℃。燃烧时发生大量黑烟。雾状粉尘的着火点为130℃，与空气混合爆炸下限12.6克/米3，易自动氧化，氧化后生成氧化树脂酸使松香颜色加深。有些松香具有易结晶的趋势，结晶松香熔点高（110～135℃），难于皂化，品质降低。松香的化学性质取决于树脂酸分子结构中的双键和羧基反应。
