Main Applications:
the production of basic solution for soles, PU size, nylon 66, and some solvents.
Adipic acid (Adipic acid), also known as fatty acid, is an important organic dibasic acid, which can undergo salt reaction, esterification reaction, amidation reaction, etc., and can condense into high polymer with binary amines or diols. Adipic acid is an important dicarboxylic acid in industry, which plays an important role in chemical production, organic synthesis industry, medicine, lubricant manufacturing, etc. Its output ranks the second among all dicarboxylic acids.
The functional group of adipic acid is carboxyl group, so it will have the properties of carboxyl group, such as salt formation reaction, esterification reaction, amidation reaction, etc. At the same time, as a binary carboxylic acid, it can also condense with binary amines or diols to form high polymer
stability
1. White crystal, smell of burnt bone. Slightly soluble in water, soluble in alcohol, ether and most other organic solvents. Sublimation, insoluble in benzene. Combustible, low toxicity. It has the general properties of acid, can be esterified to form mono - or diester, and when heated to 300ºC or more, decarboxylated to. 2. Adipic acid is stable and low toxic. Can be used as citric acid or tartaric acid, not deliquing. 3. It is irritating to the eyes and should be kept sealed. 4. It exists in flue-cured tobacco leaves, flavored tobacco leaves and flue gas. 5. Sublimation.
Mainly used
as a raw material for nylon 66 and engineering plastics. This is followed by the production of various ester products, which are used as plasticizers and advanced lubricants. In addition, adipic acid is also used as a Chemicalbook raw material for polyurethane elastomers, and as an acidifier for various foods and beverages, which sometimes outperforms citric acid and tartaric acid. Adipic acid is also used in medicine, yeast purification, pesticides, adhesives, synthetic leather, synthetic dyes and fragrances.
Storage condition
1. Seal and store under 4ºC. Keep away from fire, heat, water, moisture and sun protection.
2. Packed in woven bag with plastic lining, net weight 25kg. Store in a dry and cool place, and pay attention to rain prevention during transportation. Storage and transportation in accordance with general chemical regulations.
Chemical properties
White crystal, smell of burnt bone. Slightly soluble in water, soluble in alcohol, ether and most other organic solvents.
Apply
Adipic acid is the most useful dibasic acid in aliphatic group. Adipic acid has the commonness of aliphatic dibasic acid, including salting reaction, esterification reaction, amidation reaction and so on. The main use of adipic acid is as a raw material for three major categories of products, namely: the synthesis of nylon 66 salt, and then the manufacture of polyamide resins and fibers (nylon 66), nylon 66 is the largest end market for adipic acid; Synthetic polyester polyol for the production of polyester polyurethane; Diester adipate plasticizer. In addition, it can also be used in the production of high-grade lubricants and food additives (acid agents for food and beverage).
