Abstract: This paper expounds relation of the solvent naphtha with environmental protection, and shows that demands of society on environmental protection will be stricter day by day. Requirement of solvent naphtha of little virulence and strong dissolubility will increase greatly, solvent naphtha of halohydrocarbon and puritied petroeum benzen decrease in the market, so we put forward that the solvent naphtha of non -aromatic hydrocarbon and low aromatic hydrocarbon should be developed and it is produced by condensate, thereby increasing added value of products.
