补充资料:环烷酸
  分子式  CnH2n·1COOH
   CAS号  1338-24-5
   性质  环烷酸是一类从石油产品精制分离出来的饱和脂肪酸。分单环和多环,分子量范围180~350。本品为深棕色油状液体。精制后为淡黄色或橙色液体,有特殊气味。由于原油性质及馏分的不同,所得环烷酸的分子量、相对密度、粘度、凝点和折射率也有差异。如盘锦炼油厂生产的环烷酸(轻柴油馏分)凝固点-30~-36℃。相对密度0.960(20/4℃)。折射率nD(20℃)1.4700。几乎不溶于水,而溶于石油醚,乙醇,苯和烃类等。环烷酸是一种很弱的酸,对某些金属有腐蚀作用,与金属作用生成盐。
    毒性   本品低毒,有特殊的刺激性气味。对眼、呼吸道粘膜及皮肤有刺激性。中毒症状是头晕、周身无力、血小板减少、咽喉干、痛。游离环烷酸的LD为3.5g/kg,环烷酸的中性盐的LD为6000mg/kg。操作人员要穿戴防护用具。 经口投入LD50,小白鼠0.9g/kg,大白鼠5.4g/kg。工作场所最高容许浓度5mg/m3。 
    用途  用作生产环烷酸盐的原料及涂料干燥剂, 也用于木材、电缆的防腐
   包装储运  采用铁桶包装,每桶净重180kg。按危险品规定贮运。
