Abstract

The invention relates to the field of chemical industry, specifically to a production process of a medicine Vaseline. The production process of the medicine Vaseline specifically comprises the following steps: A, performing desulfurization, dehydrogenation and deoxygenation reaction on residual oil cerate and mechanical oil; B, cooling: cooling a high-temperature product by a first cooling unit; C, performing aromatic saturation reaction: adding a hydrofining catalyst into the cooled product to generate aromatic saturation reaction; D, performing gas and liquid separation and vacuum deodorization: separating and deodorizing the product after reaction and cooling to obtain the refined Vaseline. According to the scheme, the first cooling unit is provided, so that the product after the desulfurization, dehydrogenation and deoxygenation reaction can be cooled rapidly and uniformly and the problems in the prior art that the product is slow to cool and is cooled non-uniformly are solved.

Description

technical field [0001] The invention relates to the field of chemical industry, in particular to a production process of medical vaseline. Background technique [0002] Pharmaceutical vaseline is an important raw material for the production of pharmaceuticals, daily chemicals and other fine chemical products, so its appearance, properties, acidity, color, impurities and other indicators are better than industrial vaseline. The production process of vaseline is mainly composed of two parts: the blending of raw materials and the refining of raw materials. Since there will be more non-ideal components such as dense aromatics, sulfur, nitrogen, and oxygen heterocyclic compounds in the raw materials of vaseline, it must be deeply refined to remove them. Therefore, refining is a key step in the production of pharmaceutical vaseline. [0003] The raw materials for the production of medical vaseline mainly come from residual oil wax paste, which must contain a certain amount of met...
