Another important compound is calcium chloride, CaCl2, a colourless or white solid produced in large quantities either as a by-product of the manufacture of sodium carbonate by the Solvay process or by the action of hydrochloric acid on calcium carbonate. The anhydrous solid is used as a drying...
Production methodCalcium carbonate calcination first apply calcium carbonate for reaction with hydrochloric acid to generate calcium chloride, followed by addition of ammonia for neutralization, standing for precipitation and filtration, followed by adding sodium bicarbonate for reaction to generate calcium carb...
it can be obtained by reaction of calcium carbonate and hydrochloric acid. it can be obtained by the rectification of by-products in the production of sodium hypochlorit. category toxic chemicals. toxicity grading medium poison. acute toxicity oral-rat ld50: 1000 mg/kg; oral-mouse ld50: 1940...
The sample was prepared by dissolving it in 1N hydrochloric acid, and then filtrating. The amount of peptide contained in pGlu–HAp was calculated by simultaneous thermogravimetry and differential thermal analysis (TG-DTA; Thermo Plus TG 8120, Rigaku Co., Tokyo, Japan). The temperature was ...
This assay was based on the addition of concentrated hydrochloric acid (HCl) to the magnetic NPs to promote the formation of iron(III) chloride complexes with a strong signal in the UV-Vis range [64]. First, the previously synthesized MLs (following the procedure described in Section 2.3) ...
In a word, all inhibitors tested in this research could decrease both general corrosion and localized corrosion for Q235 carbon steel in the test environment. CLS has a better effect on inhibition of the initiation of pitting corrosion, and the inorganic inhibitors could promote the re-passivation...
