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).
