pyromucic acid - Upstream Downstream Industry
pyromucic acid - Introduction
furoic acid, white monoclinic long rhombic Crystal, slightly soluble in cold water, soluble in hot water, ethanol and ether, can be used for the synthesis of methyl furan, furfural amide and furoate Ester and salt; in the plastic industry can be used as plasticizers, thermosetting resin, etc.; In the food industry as a preservative; Can also be used as coating additives, pharmaceutical and perfume intermediates.
biological activity
2-Furoic acid (2-furancarboxyic acid, Pyromucic acid, 2-Carboxyfuran, α-furancarbonic acid, α-furoic acid) is an organic compound widely used in food production as a preservative and flavor enhancer.
chemical properties
white monoclinic long spindle crystal. Melting point 133-134 °c. Boiling point 230-232 °c, 141-144 °c (2.62kPa). 1g of the product can be dissolved in 26ml cold water or 4ml boiling water, soluble in ethanol and ether. Sublimation at 130-140 °c (6.65-8kPa).
uses furoic acid is used in the synthesis of methyl furan, furfuramide and furoate esters and salts. In the plastic industry can be used for plasticizers, thermosetting resins and so on. It is used as a preservative in the food industry, and also used as a coating additive, medicine. Intermediates of spices, etc.
Uses of organic synthetic raw materials, widely used as pharmaceutical, perfume intermediates, can also be used as preservatives and fungicides
production method
from the sugar aldehyde by air oxidation. The reaction was carried out at 45 °c with vigorous stirring. The reactant is filtered to recover the Catalyst Copper oxide, and the filtrate is acidified with 50% sulfuric acid to a pH of 3-2.5, suction filtered, washed with water, and dried to obtain furoic acid. Furfural in neutral or alkaline medium, with sodium hypochlorite or potassium permanganate oxidation 2H, then hydrochloric acid acidification, can also be prepared furoic acid, the yield of right up to 98%.
