Acid coating cross-linking agent: including organic acid, acid anhydride, and boron trifluoride and its complex.
Organic acids refers to some acidic organic compounds. Is the most common organic carboxylic acid, the acid is the result of carboxyl (-cooh) group. Sulfonic acid (- SO3H), the sulfonic acid (RSOOH), sulfur, carboxylic acid (RCOSH) also belongs to organic acid, etc. Organic acid can react with alcohol ester.
Organic acid can react with alcohol ester. Carboxyl is carboxylic acid functional groups, in addition to formic acid (-cooh) group H a, carboxylic acids can be seen as hydrocarbon molecules after hydrogen atoms are replaced by carboxyl of derivatives. Available general formula (Ar) R - COOH said. Carboxylic acid in nature in the form of a free state, with salt or ester is widespread.
Alkyl carboxylic acid molecules in the derivative of the hydrogen atoms are replaced by other atoms or groups of atoms called replace carboxylic acid. The important place of carboxylic acid have halogen acid, hydroxy acid, acid and amino acid etc. A part of the compounds involved in the metabolism of plant and animal life hydroxyl, some are metabolic intermediate, some significant biological activity, can prevent and cure, some of them are in organic synthesis, industrial and agricultural production, and pharmaceutical raw materials.
Organic acid were significantly more soluble in water or ethanol acid reaction, hardly soluble in other organic solvents. Are volatile or not. Adding calcium chloride in organic acid aqueous solution or lead acetate or barium hydroxide solution, can generate insoluble in water, calcium salts and lead salt or barium salt precipitation.
Generally think aliphatic organic acid no special biological activity, but some organic acids such as tartaric acid, citron acid as a medicinal. Malic acid and the report suggests, citron acid, tartaric acid, ascorbic acid and other comprehensive functions of central nervous. Some of the special acid is an effective ingredient of some herbal medicine, such as soil park park in soil "leather acid have antifungal effect. Have certain biological activity of caffeic acid derivatives, such as Chlorogenic acid (Chlorogenic acid) for a variety of active ingredients of Chinese herbal medicine. Has antibacterial, cholagogue function, elevated white blood cell, and so on.
Carboxylic acid functional group is carboxyl, in addition to formic acid, are made by hydroxyl and carboxyl of two parts. According to different alkyl structure, divided into fatty acids and aromatic acids. Carboxyl and hydroxyl connected fat, known as fatty acid; Saturated fatty acids according to hydrocarbon saturation not divide again ester fat acids and unsaturated fatty acids. If not containing unsaturated bond in the fatty hydrocarbon, it is called a saturated fatty acid; If fat hydroxyl containing unsaturated bond, referred to as the unsaturated fatty acid.
Chinese name: Diethyl toluene diamine(DETDA)
Diethyltoluenediamine Raw material ：
TDA industrial, Sichuan production
Ethylene (Et) polymer grade, Shanghai production
TEA industrial imports
A reagent grade additives
Carboxylic acid and aromatic hydrocarbon connected, known as aromatic acid. Carboxylic acids can also according to their molecular contained carboxyl divided into monocarboxylic acids, the number of binary carboxylic acids and carboxylic acid. Molecules containing a carboxyl group called monocarboxylic acids; Molecule contains two carboxyl called binary carboxylic acid: the molecule contains two or more carboxyl acid are collectively referred to as diverse carboxylic acid.
The common name and system named commonly used carboxylic acid. Common name is commonly used by its source and, such as carbonization ants get formic acid (formic acid), acetic acid from making vinegar (acetic acid). Oil ester hydrolysis get higher fatty acid, palmitic acid, palmitic acid, stearic acid, oleic acid, linoleic acid and linolenic acid, etc.
Anhydride is a oxyacid off a molecule of water or a few molecules of water, the rest part. General inorganic acid is a member of the acid, lose a molecule of water is directly form the acid anhydride, its decide acid anhydride the combining power of the elements of the same. And organic acid is more than two molecules of the acid or molecules of the acid by intermolecular dehydration reaction. Only oxygen acid anhydride. There is no anhydride of anaerobic acid.
Acid anhydride is considered to be a general by dehydration of oxide (organic acid anhydride do not belong to the oxide). Many can function as the original acid with water.
According to the nature of the acid can be divided into: (1) the inorganic acid anhydride, shrink by one or two acid molecules. Such as carbon (acid) anhydride is carbon dioxide, CO2 (acid) anhydride nitrate nitrogen N2O5 pentoxide. (2) organic acid anhydride, made up of two unary acid molecules or shrink and become a dibasic acid molecules compounds, is not oxide, also known as acid anhydride. Such as b (acid) anhydride (CH3CO) 2 o, C8H4O3 phthalic anhydride, etc.
