3,5-Dinitrobenzoic acid Chemical Properties,Uses,Production
Chemical Properties
White to pale yellow monoclinic prismatic crystal. Soluble in alcohol and glacial acetic acid, slightly soluble in water, ether and carbon disulfide. Can be volatile with water vapor.
Uses
3,5-Dinitrobenzoic acid, is used as a reagent used in the derivatization of resins and the determination of ampicillin.
Preparation
3,5-Dinitrobenzoic acid is synthesized by nitration of benzoic acid. Sulfuric acid was added to the dry reaction pot, and benzoic acid was added under stirring. Heat to 60°C, add fuming nitric acid dropwise, and complete the dropwise addition below 85°C. React at 80-85°C for 1 h, 100°C for 0.5-1h, and then heat up to 135°C for 2h. Leave overnight. The reaction solution was put into ice water to separate out crystals, filtered, washed with water and then washed with 50% ethanol to obtain 3,5-dinitrobenzoic acid. Yield 70%.
Definition
ChEBI: 3,5-dinitrobenzoic acid is a member of the class of benzoic acids that is benzoic acid in which the hydrogens at positions 3 and 5 are replaced by nitro groups. It is a C-nitro compound and a member of benzoic acids.
General Description
3,5-Dinitrobenzoic acid forms an adduct with 3,5-dimethylpyridine and the crystal structure of adduct has been studied at room temperature and 80K for both undeuterated and deuterated compounds. It forms 1:1 cocrystal with analgesic drug, ethenzamide and exists in two polymorphic forms.
Purification Methods
Crystallise the acid from distilled H2O or 50% EtOH (4mL/g). Dry it in a vacuum desiccator or at 70o over BaO under a vacuum for 6hours. [Beilstein 9 II 279, 9 III 1779, 9 IV 1242.]
