The nature and use
of oil chemical industry
oil chemical industry is an important chemical field, mainly related to the production, processing, modification and application of oil. A wide range of oil chemical raw materials, including animal and vegetable oils, fatty acids, glycerol, esters and other substances. These raw materials can be converted into various oil chemical products through different chemical reactions and processing technologies, which are widely used in food, medicine, daily chemicals, energy and other fields.

1. oil chemical properties

1. fatty acid properties

oil is the main component of fatty acid glyceride, which has different carbon chain length and degree of unsaturation. The properties of fatty acids include melting point, boiling point, solubility, acidity and alkalinity, which are closely related to the length of the carbon chain and the degree of unsaturation. In general, the longer the carbon chain, the higher the melting point; the higher the degree of unsaturation, the lower the melting point.

2. glycerol properties

glycerol is an important raw material in oil chemical industry, with three hydroxyl groups, can occur esterification, etherification, oxidation and other reactions. The properties of glycerol include viscosity, boiling point, hygroscopicity, etc. These properties are related to the purity and molecular structure of glycerol.

3. Ester properties

esters are an important part of oleochemical products, including fatty acid esters, glycerides and so on. The properties of esters are related to their structure, and generally have good chemical stability and thermal stability, as well as certain solubility and surface activity.

2. oil chemical use

1. food field

oil chemical industry in the food field has a wide range of applications, mainly as food additives and processing aids. For example, hydrogenated vegetable oil is a common food additive, which can be used as shortening, margarine, etc.; at the same time, some esters can also be used as food additives, such as ethyl acetate can be used to make flavors, and glycerol can be used as sweeteners and moisturizers.

2.

in the field of medicine Oleochemicals also have important applications in the field of medicine, mainly as drug carriers and excipients. For example, some fatty acid glycerides can be used as drug carriers to improve the solubility and bioavailability of drugs; at the same time, some esters can also be used as drug excipients, such as polyethylene glycol can be used as a drug solubilizer and emulsifier.

3.
in the field of daily chemical
oil chemical industry in the field of daily chemical also has a wide range of applications, mainly as skin care products, cosmetics raw materials. For example, some animal and vegetable oils can be used as base oils for skin care products, with moisturizing and moisturizing effects; at the same time, some fatty acids and esters can also be used as cosmetic formulation ingredients, such as stearic acid can be used as emulsifiers and thickeners.

4.

in the energy field Oleochemicals also have certain applications in the energy field, mainly as raw materials for biodiesel. Some animal and vegetable oils can be converted into biodiesel by transesterification reaction, which has the advantages of renewable and environmental protection.

In short, oil chemical industry has a wide range of applications in various fields, providing important material support and guarantee for people's production and life.
