Usage

General Description

Pentaerythritol monostearate is a chemical compound commonly used as an emulsifier in food, pharmaceutical, and cosmetic products. It is derived from pentaerythritol, a polyalcohol, and stearic acid. Pentaerythritol monostearate acts as a stabilizing agent, helping to mix and disperse oil and water components in a product, preventing them from separating. It is also used as a lubricant in the production of plastics and as a release agent in the manufacturing of rubber. Additionally, pentaerythritol monostearate is utilized as a thickening agent in the formulation of various beauty and personal care products, such as lotions, creams, and makeup. Due to its versatility and stability, pentaerythritol monostearate is a widely used and effective ingredient in a variety of industries.

Solid supported type ion liquid catalytic synthesis of stearic acid pentaerythritol ester of method

The present invention discloses a solid supported ionic liquid catalytic synthesis of stearic acid pentaerythritol ester of method, characterized in that in order to stearic acid and pentaerythritol as the raw materials, to solid supported type imidazole ion liquid as the use of the catalyst. The invention adopts the sol-gel process solid-ionic liquid, the catalyst amount is alcohol, acid always mole number of 1% - 5%, the reaction temperature is at 110 - 170 °C, normal pressure, reaction time 1 - 5 h; the characteristic of this invention is not adopted the pollution to the environment of the concentrated sulfuric acid, with the traditional inorganic acid as compared with the catalyst, solid-ionic liquid has high catalyst activity, mild reaction, esterification rate high, obtained by the production process is simplified, catalyst recovery simple operation and the like.

Plastic lubricant synthesis method

The invention discloses a plastic lubricant synthesis method. The method is characterized in that pentaerythritol and stearic acid are taken as raw materials and are matched according to the molar ratio of 1:4, esterification reaction is conducted at 150-220 DEG C in the air atmosphere with a small amount of water separating agent under the catalysis of the solid catalyst stannous oxide or zinc oxide, and filtration is conducted about one hour later to obtain pentaerythritol stearate, wherein the weight of the solid catalyst stannous oxide or zinc oxide is 0.1-2% that of stearic acid. The adopted solid catalyst has high catalytic property, does not cause corrosion to equipment and can be repeatedly used after filtration. Meanwhile, a small amount of xylene is adopted as the water separating agent, so that a reaction system is maintained to be at a high temperature where stannous oxide catalysis efficiency is high and reaction raw materials and products can not be oxidized or carbonized. Besides, the post-treatment method is simple, washing is not needed, and the requirement for green chemistry is met. The synthesis method is high in yield, color is good, purity is high, cost is low, and application prospects are broad.
