CO2 absorbing solution such as seawater or an alkali solution through a cation exchange membrane 2 (e.g. an ion exchange membrane containing a sulfone group and/or carboxylic acid group as an ion exchange group such as a fluorine type cation exchange membrane) to absorb CO2 from said gas 1...
Concentrate composition to remove colored performs a sanitizing includes peracetic acid, preferably acetic acid, and hydrogen peroxide. They can be incorporated, at a concentration in the range of from 4,000ppm 600ppm, to use the construct rinse sanitizing this preferably....
Re: How best to start esterification? «Reply #4 on:October 14, 2019, 02:00:16 PM » Yes its a good idea to remove water but if you can use the alcohol as a solvent, just reflux it together with some sulphuric acid. Few drops might be enough but sometimes more is neded ...
To analyze the carbonyl group content in untreated or LPMO-treated cellulose fibers, i.e., reducing-end aldehyde groups and 4-keto groups resulting from C4-oxidation, 20–25 mg dry cellulose samples were reacted with the fluorescent label carbazole-9-carboxylic acid [2-(2-aminooxyethoxy)ethoxy...
Thianaphthene-2-carboxylic acid and its derivatives are widely used in the fields of pharmaceuticals, pesticides, and as important intermediates for ..

Mature biofilms are difficult to remove mechanically due to the enhanced viscoelasticity conferred by EPS42. EPS may achieve immune evasion by...

carboxylic acid (febuxol Tan, an effective anti-gout drug). Ethyl 2-bromothiazole-5-carboxylate is used as raw material and then hydrolyzed through substitution reaction to obtain 2-[2-(4-chloro-5-ethyl-1-hydrimidazole)-amide-1-(3-methoxypiperidine )] -4-methylthiazole-5-carboxylic acid ...
and adjust the pH to around 2 using concentrated hydrochloric acid. A large amount of white solid will precipitate. Extract with 50ml of ethyl acetate three times, dry with anhydrous magnesium sulfate, and remove the solvent by vacuum distillation. Precipitate with petroleum ether to obtain Fmoc-...
