抽余油是50～220℃直馏汽油组份为原料,经催化剂(铂或铼)和加氢使烃类化合物分子结构重整。提取芳香烃后剩余的混合烃类(含C_5～C_(10))化合物。由于其芳香烃含量少(一般小于5％,苯小于1％),毒性较低,主要作为工业有机溶剂,稀释剂和植物油提取剂等取代苯系化合物和三氯乙烯等高毒有机溶剂,广泛用于造漆、喷漆、橡胶粘合剂、印刷、油墨、食物油提取,制鞋及清洗机械油垢等生产领 Raffinate oil is 50 ~ 220 ℃ straight-run gasoline component as raw material, the catalyst (platinum or rhenium) and hydrogenation of hydrocarbon molecular structure reforming. The remaining mixed hydrocarbon (including C_5 ~ C_ (10)) compounds after aromatics extraction. Because of its low aromatic content (generally less than 5%, less than 1% benzene), low toxicity, mainly as industrial organic solvents, thinners and vegetable oil extractants such as substituted benzene compounds and trichlorethylene and other highly toxic organic solvents, a wide range For the manufacture of paint, paint, rubber adhesives, printing, printing ink, food oil extraction, shoe and cleaning machinery grease and other production collar
