CHARACTER

lauric acid, chemical formula C12H24O2, is a white crystalline waxy solid with a slight fatty aroma. Lauric acid is one of the important fatty acids, widely used in surfactants, detergents, cosmetics, food and plastics industries. In the manufacture of surfactants, lauric acid is used to synthesize anionic surfactants to improve the cleaning ability of products; in detergents and cosmetics, it is used as an emulsifier and thickener to improve the stability and use experience of products; in addition, lauric acid is also used in the manufacture of food emulsifiers and preservatives, and plasticizers in plastic processing. As a multifunctional organic compound, lauric acid is widely used in many industrial fields and is an indispensable raw material in modern industry.

APPLICATIONS

(1) Lauric acid plays an important role in the daily chemical industry. It is one of the main components of soap and detergent. It can effectively remove stains and grease and keep it clean and hygienic.

(2) In the food industry, lauric acid can be used as a food additive, such as in the processing of edible oil, which can improve the taste and stability of food. At the same time, because lauric acid is a kind of medium-chain fatty acid, it is easy to decompose and not easy to accumulate into fat, so it is also used in some health foods.

(3) Lauric acid is also used in the pharmaceutical industry. It can be used as an intermediate in the synthesis of drugs and participate in the synthesis of some pharmaceutical ingredients with antibacterial and antiviral activities.

(4) In addition, lauric acid is also widely used in the manufacture of surfactants, wetting agents, pesticides, cosmetics, alkyd resins, chemical fiber oil agents, plastic stabilizers and anti-corrosion additives for gasoline and lubricants, showing its wide range of applications and important industrial value.

Introduction

Lauric acid is an organic compound. Its nature is a colorless crystalline flake solid with a special aroma and bitter taste. It is insoluble in water, but soluble in organic solvents such as ethanol.

lauric acid has a variety of uses. There are two common methods for the preparation of

lauric acid. One is prepared by the emulsification decomposition method, the reaction of lauryl alcohol with an oxidant; the other is prepared by the oxidation reaction of lauryl alcohol.

lauric acid safety information: it belongs to the low toxicity compound, under normal circumstances harmless to the human body. Ingestion in large quantities may cause gastrointestinal discomfort. During use, direct contact with skin and eyes should be avoided, and appropriate protective equipment should be worn when using. In addition, lauric acid should be kept away from fire and high temperature, storage should be sealed to avoid mixing other chemicals. If inhalation or ingestion occurs, seek medical attention immediately.

 

preparation method

Industrial production methods can be divided into two categories: one is made from natural vegetable oils by saponification or high temperature and high pressure decomposition; the other is separated from synthetic fatty acids. The natural vegetable oils used to produce dodecanoic acid include coconut oil, sunsea beba kernel oil, palm kernel oil and mountain pepper kernel oil.
