石油萘下游产品的开发和利用

Development and utilization of Petronaphthalene Derivate

基于石油甲基萘和石油萘来源的特殊性，在吸收煤焦油甲基萘和萘制备分散剂MF和 水泥减水剂原有工艺的基础上，将乙烯焦油进行提炼得到石油萘的下游产品──甲基萘与萘 ，来制备分散剂MF和水泥减水剂。

Start with the extract of petronaphthalene derivate,methylnaphthalene and naphthalene from ethylene－tar,and in view of their specialities from coal tar extracts and the original technique for Disperser MF and Cement－disperser.
