Daqing Kunlun brand 58 semi-refined paraffin

Ketone benzene dewaxing principle is the use of oil and wax in the selective mixed solvent solubility is different, under crystallization conditions, mixed solvent diluted oil, and can dissolve the oil and it is difficult to dissolve the wax, so that the wax in the solution of supersaturation and crystallization precipitation, Z after the method of filtering the oil wax separation.

First, the main composition of paraffin

Paraffins are mainly composed of normal (straight chain) alkanes above C15, but also contain a small amount of isomeric alkanes or alkanes with long side chains.

Two, the melting point of paraffin

The melting point of paraffin wax is a main index to judge the grade of paraffin wax. For example, the melting point of No. 58 paraffin shall not be lower than 58℃ and no higher than 60℃.

Three, the stability of paraffin

Stability is divided into light stability and thermal stability.

The petroleum wax should have good heat and light stability. Otherwise, for a long time with hot air or direct sunlight, paraffin wax will gradually oxidize and deteriorate, the color becomes dark, and even the odor becomes large.
