Amberic acid

Succinic acid [110-15-6] (butanedioic acid 1,2-ethanedicarboxylic acid amber acid), occurs frequendy in nature as such or in the form of its esters. 

The second type of mechanism offers reversible switching without space-consuming transfer processes. These dyes are electrocyclically reacting dyes, where the transition from one form to another form happens by electron shift or proton transfer, without the rearrangement of bulky molecule segments. Fulgides have been proposed for this purpose. Fulgides are bis (methylene) amber acid anhydrides (130), eg,...

Citric acid with three -COOH and one -OH groups and tartaric acid with two -COOH and two -OH groups are excellent depressants, oxalic and amberic acid possessing two COOH groups also exhibit good depression, but the two -CH2- groups on the latter molecule reduces its hydrophilicity acetic acid and lactic acid which have only one -COOH group are very weak depressants. 

AMBER ACID (110-15-6) Combustible solid. Dust or powder may form explosive mixture with air. Violent reaction with strong acids, strong oxidizers. Decomposes in elevated temperatures above 455°F/235°C, forming succinic anhydride. Incompatible with sulfuric acid, caustics, ammonia, aliphatic amines, alkanolamines, isocyanates, alkylene oxides, epichlorohydrin, oxidizers. 

Succinic acid [110-15-6] (butanedioic acid 1,2-ethanedicarboxylic acid amber acid), C4H604, occurs frequendy in nature as such 01 in the form of its esters. It can be found in animal tissues (1), in vegetables and fruit (2,3), or in spring water (4), and has also been identified in meteorites (5). It is formed in alcoholic fermentation (6) and in the chemical and biochemical oxidation of fats. Succinic acid is present in amber (7) (Succinum) and can be obtained by distillation, by which method it was first isolated by Georgius Agricola in 1550. 

Succinic acid, known as amber acid or butanedioic acid, is a four-carbon dicarboxylic acid produced as an intermediate of the tricarboxylic acid cycle (TCA) [1,2]. Succinic acid and its derivative have wide industrial applications such as the feedstock of food and pharmaceutical products, as the intermediate of chemical synthesis of surfactants, detergents, green solvents, and biodegradable plastics, and also as ingredients of animal feeds to stimulate animal and...

Succinic acid (SA) is a dicarboxylic acid that is also called amber acid or butanedioic acid. It is a tricarboxyhc acid (TCA) cycle intermediate that is produced in various organisms. Because of its wide application value in the market, demand is increasing, which has boosted the production scale of SA. 

De Morveau introduced the name acide pnissique, he called uric acid acide lithiasique or adde lithique, and succinic acid (which he obtained crystalline by distilling amber) acide karabique.At first he thought prussic acid was a compound of a radical, containing the volatile alkali and phlogiston, with...

Succinic acid (ethane-1,2-dicarboxylic acid) is also known as amber acid with an International Union of Pure and Applied Chemistry name of butanedioic acid. It is a dicarboxylic acid (saturated) with the chemical formula of HO2C (CH2)2C02H, and its chemical structure is illustrated in Fig. 9.3. The acid and its esters occur in nature in amber, spring water, meteorites, vegetables, and fruit and animal tissues. The production methods generally include the biochemical and chemical oxidation of fats and alcoholic fermentation. In its pure form, succinic acid occurs as colorless triclinic prisms (a-form) and monoclinic prisms (p-form) (Fumagalli, 2007). Some of the significant properties of succinic acid are summarized in Table 9.2.
