The impact of chloroacetic acid purity on the production of carboxymethyl cellulose
Where is the expert? Brothers and sisters, please give your support! !
{:3_55:} The main impurities in chloroacetic acid are dichloroacetic acid, along with acetic acid. Manufacturers are generally able to control the level of acetic acid, while the level of dichloroacetic acid usually exceeds 0.3%. When producing CMC, the content of dichloroacetic acid is important to consider, as it affects the viscosity; this is probably related to the fact that chloroacetic acid has a functional group count of 2, meaning two hydroxyl groups are converted into one carboxyl group
Could you be more detailed? I read an article stating that a higher dichlorine content leads to an increase in the viscosity of cellulose
Is there a process flow for producing methyl acetate using chloroacetic acid mother liquor? Could someone share it with me? I’d like to learn about it; my company plans to implement this project soon :)
