Embodiment 1

[0019] The decolorizing agent 3 that the present invention selects is loaded with ZrO 2 and ZnO activated carbon, where ZrO 2 and the loadings of ZnO are expressed by weight percent relative to activated carbon, ZrO 2 The loading amount of ZnO is 4%, and the loading amount of ZnO is 1%.

[0020] The depth decolorization method of diisostearyl malate comprises the following steps:

[0021] Prepare decolorizing agent 3 by dipping method;

[0022] Pretreatment of decolorizing agent: put 50g of decolorizing agent into a fixed bed heated by electric charge, fill the top and bottom of decolorizing agent 3 with quartz sand, heat the bed layer containing decolorizing agent 3 to 350°C, and at the same time continuously feed hydrogen gas 1 to treat 4 Hour.

[0023] Decolorization treatment: cool down the bed layer containing the decolorizing agent 3 and maintain it at 100°C, while heating the diisostearyl malate 2 to 100°C, stop feeding the hydrogen gas 1, and heat the heated diisos...

Abstract

The invention discloses a diisostearyl malate decolorizing agent and a deep decolorizing method of diisostearyl malate. The deep decolorizing method comprises the following operation steps that firstly, the decolorizing agent is put into a stationary bed to be preprocessed; secondly, the diisostearyl malate is heated and led into the stationary bed filled with the decolorizing agent to carry out decolorization, and a target product is obtained after filtering is carried out. The decolorizing agent is nontoxic and harmless, low-color-scale diisostearyl malate can be prepared, the decolorizing agent has the chemical reducibility after being treated through hydrogen gas, oxygen dissolved in the diisostearyl malate can be consumed, survival of microorganisms is inhibited, and the product can have the longer fresh scent and longer shelf life, According to the deep decolorizing method of the diisostearyl malate, the integral operation process is simple, and the low-color-scale diisostearyl malate can be quickly prepared.

Description

technical field [0001] The invention belongs to the application field of fine chemicals, and in particular relates to a decolorizing agent for diisostearyl malate and a deep decolorizing method. Background technique [0002] Diisostearyl malate is an important raw material for cosmetics, which has the functions of lubricating, dispersing and bonding, and is widely used in lipsticks, lotions, hair care products, etc. In order to better apply diisostearyl malate in cosmetics, it needs to be decolorized to meet the requirements of different use conditions. In industry, activated carbon or activated clay is usually used for decolorization. However, the existing decolorization methods cannot reduce the chroma of diisostearyl malate better, so it is of great significance to study an effective deep decolorization method to meet the production requirements. [0003] In view of the defects in the above-mentioned existing diisostearyl malate decolorization method, the inventor is ba...
