Embodiment Construction
[0008] The present invention is described in further detail below: a kind of production technology of medicine petrolatum, it comprises the following steps:
[0009] (1) Light dewaxing paste and white oil are selected as raw materials. The light dewaxing paste is 15# light dewaxing paste, and the white oil is 55# white oil. The light dewaxing paste and white oil are obtained by heating and reacting crude petroleum jelly;
[0010] (2) Add a thickener and a catalyst to the obtained vaseline crude product, the light dewaxing cream: white oil: thickener: catalyst in a ratio of 10:9:2:1 by weight, wherein the The thickener is loose wax, the catalyst is microcrystalline wax, the temperature is controlled at 90-110 ° C for 2 hours, and the compressed air is used to stir, that is, the compressed air is blown from bottom to top for 30 minutes, and the product is obtained. Medicine vaseline.
[0011] The pharmaceutical vaseline produced by this process is compared with Chinese Phar...

The invention relates to a production process for vaseline, in particular to a production process for medicinal vaseline, which belongs to the field of medicine. In order to solve the problems of high production cost, high impurity content, low quality and high pollution in the prior art, the production process for the medicinal vaseline comprises the following steps: (1) selecting raw materials including hydrogenation dewaxing paste and white oil and reacting the hydrogenation dewaxing paste with the white oil under heating to obtain a vaseline crude product; and (2) adding a thickening agent and a catalyst into the obtained vaseline crude product and stirring to obtain the medicinal vaseline. Compared with the prior art, the production process for the medicinal vaseline has the following advantages: the hydrogenation dewaxing paste and the white oil are adopted as the main raw materials, the thickening agent and the catalsyst are added after the heating reaction and no organic solvent is used in the process, the waste of the raw materials is avoided, the production cost is low, the product quality is high, the production period is short, environmental pollution is avoided, hydrogen source is not used, and the effects of safety and environmental friendliness are achieved.
Description
technical field [0001] The invention relates to a production process of vaseline, in particular to a production process of medical vaseline, which belongs to the field of medicine. Background technique [0002] The traditional process uses three methods: acid-clay method, aluminum trichloride method, and high-pressure hydrogenation method. After decades of experiments, the yield of acid-clay method is only 50% and a large amount of unusable acid slag is produced. Serious environmental pollution and high production costs; the quality of the aluminum chloride method is poor; although the high-pressure hydrogenation method solves the above pollution problems, the production cost is high, there are major safety hazards, and a large amount of hydrogen is needed, and the hydrogen source is not easy to obtain. This restricts the implementation of this method. Contents of the invention [0003] The purpose of the present invention is to provide a production process of medical vas...
