The chemical reaction process for sodium carboxymethyl cellulose (Na-CMC) production by treating the glucose polymer cellulose with chloroacetic acid
under basic conditions.4
Reagents (analytical grade): 5,5'-Dithiobis(2-nitrobenzoic acid (DTNB), (2-Mercaptoethyl) trimethylammonium iodide (thiocholine iodide), 1-chloro-2,4-dinitroben zene (CDNB), reduced glutathione (GSH), Tri chloroacetic acid
(TCA), Thiobarbituric acid (TBA), Tris-HCl, Diethylene triamine pentaacetic acid (DTPA), buthylated hydroxytoluene (BHT) dipotassium phosphate and monopotassium phosphate, Bradford reagent and the Bovine g-globulin.
The investigators adjusted the pH to 3.5 with chloroacetic acid
In order to distinguish ionic crosslinks from covalent crosslinks, samples were swollen in the mixture of xylene and chloroacetic acid
for five days to destroy ionic crosslinks, followed by swelling in xylene for two days, weighed, then vacuum dried and reweighed.
Luo, One-pot synthesis of 3,4-dihydropyrimidin-2(1H)-ones using chloroacetic acid
as catalyst, Bioorg and Med.
Increases in absorbance a 470 nm were recorded after adding 2.0 mL of 20% chloroacetic acid
. APOX (EC 188.8.131.52) activity was determined according to the method reported by Nakano and Asada (1981).
8.6 g chloroacetic acid
(Aldrich) was added and the: pH was adjusted to 12.
Through our unremitting efforts, a provide a simple, efficient and inexpensive one-pot method for the novel thiadiazole derivatives synthesized using 2-substituted [1, 3, 4] thiadiazole, P2O5 and chloroacetic acid
as materials by using XH-200A computer microwave solid-liquid phase synthesizer, although the compounds can improve the anti-corrosion efficiency, but it is different to prepared on a large scale .
