A production process of acetic acid according to the present invention inhibits concentration of hydrogen iodide and improves a liquid-liquid separation of an overhead from a distillation column. Acetic acid is produced by distilling a mixture containing hydrogen iodide, water, acetic acid and methyl...
PROBLEM TO BE SOLVED: To provide a method for producing acetic acid capable of efficiently separating acetaldehyde and methyl iodide and reducing the loss of methyl iodide. SOLUTION: In the process of producing acetic acid, the production of acetic acid comprising a membrane separation step of ...
1. A process for the production of 2,4,5-trichlorophenol analytically free of 2,3,7,8-tetrachloro-dibenzo-p-dioxin consisting essentially of nitrating 1,2,4-trichlorobenzene with an acid selected from the group consisting of: (a) fuming nitric acid at a temperature of from 30° C. to 55...
These findings are in accordance with Zou [58] who observed no significant acid production during natural aging of paper. In conclusion, irrespective of the specific chemical processes that give rise to the presence of acetic acid, the impact of airborne acetic acid is sufficiently modeled by ...
Programmed cell death (PCD) induced by acetic acid, the main by-product released during cellulosic hydrolysis, cast a cloud over lignocellulosic biofuel fermented by Saccharomyces cerevisiae and became a burning problem. Atg22p, an ignored integral membr
A process for removing water from an acetic acid stream in the production of alcohols, such as ethanol produced by hydrogenating acetic acid. Water is removed from the acetic acid stream using an adsorption unit, membrane, molecular sieves, or a combination thereof, to form a return stream. ...
A method is disclosed for controlling a methanol carbonylation process for producing acetic acid. The method includes the steps of monitoring the rate of production of the acetic acid; reducing the pr
