Safe Carbonyl Acetic Acid for Food Industry

Safe Carbonyl Acetic Acid for Food Industry

Edible acetic acid (Also as glacial acetic acid) I. Edible acetic acid is classified into two types: 1.Acetic acid in alcohol process (Also as Alcoholic acetic acid) .  2.Carbonyl acetic acid. II. The characteristics and applications of Carbonylation synthesis of acetic acid:  High-efficiency industrial production involves the reaction of methanol (CH₃OH) and carbon monoxide (CO) as raw materials under the action of a catalyst such as rhodium or iodide to form acetic acid. Economic and environmental protection: The raw materials methanol and CO have low costs and can be sourced from coal chemical industry or natural gas reforming. Compared with the fermentation method, it has a shorter production cycle and lower energy consumption. Food industry: Diluted as edible vinegar (must meet food-grade standards). Acidulants and preservatives (such as soy sauce, pickled products).
