SU761546A1 - Vaseline - Google Patents

Description

The invention relates to vaseline 'and can be used in the petrochemical industry, in particular in the electrical industry and agriculture.

Vaseline is known, consisting of a May- ⁵ lian base - a mixture of petrolatum with mineral oil, paraffin and ceresin '

M ·

To reduce the content of aromatic hydrocarbons and improve color, petroleum jelly is subjected to deep cleaning with sulfur. acid and bleaching clay.

The lack of vaseline is a relatively high cost due to the need for cleaning and the use of mineral May. ^la ·

Nel invention increase the production of petrolatum.

This goal is achieved by the fact that the well-known petrolatum, consisting of an oil base, paraffin and ceresin, contains as an oil base the gach from the dewaxing of white technical oils with

The following ratio of components, wt.% :. ·

Gach 82.0-80.5

Paraffin 1.6-5.6

Ceresin 7.9–12.4

The proposed petrolatum is obtained

the offset of the above components at 60-80 ° C.

Vaseline meets the requirements of GOST 5774-76 and GOST ’13037-67 on

Introduction of vaseline Gacha from the dewaxing of white technical oils consisting of 95-96% of naphthenic-paraffin and 5-4% of aromatic hydrocarbons 30 and characterized by color 1 unit of CNT, allows to obtain the above product without additional purification with sulfuric acid and bleaching clay , which eliminates non-utilizable 35 production wastes in the form of acid tar and spent bleaching earth.

Claims (1)

Claim Petroleum jelly, consisting of an oil base, paraffin wax and ceresin, I distinguish · " due to the fact that, in order to increase the production efficiency of vaseline, it contains as an oil base the gach from the dewaxing of white technical oils in the following ratio of components, wt.%: Paraffin 1.6-5.6 Ceresin 7.9-12.4 Gach Else
