Abstract:
A method of liquefying and dispersing crystalline wax in a petrochemical mixture, comprising the steps of:(a) chemically treating the crystalline wax in the petrochemical product to reduce the surface tension of the crystalline wax, converting it to an amorphous form of wax, and treating the crystalline wax in the petrochemical mixture with a surface active agent having a surface tension in water in the range of about 10 to about 48 dynes per cm, reducing the crystalline wax's surface tension, including with the surface active agent in a homogeneous mixtureâ€”about 15% to about 35% by weight butyl cellosolve; and about 5% to about 15% by weight of pine oil and a mixed catalyst solution made of saturated higher fatty acids, an alkyl phenol and an oil-water soluble copolymer of partially sulfonated, maleic anhydride and polystyrene with a molecular weight ranging from about 2,000 to about 2,000,000; and (b) dispersing the amorphous wax in a diluent.
