A solidification matrix includes a straight chain saturated carboxylic acid salt, sodium carbonate, and water. The straight chain saturated carboxylic acid salt is selected from a salt of a mono-, di-, or tri-carboxylic acid. The solidification matrix ma
The ethyl ester may be formed from the acetimidic acid with Na2CO3 under reduced pressure, and the hydrazide by heating the ester with hydrazine hydride. The acid chloride may be formed by treating the acid with thionyl chloride, and the anhydride from the acid chloride and its sodium salt ...
into the saturated Na2CO3 solution, prevent the breath.The effect of saturated Na2CO3 solution: absorption of volatile acid; dissolved volatile alcohol; reduce the solubility of ethyl acetate.The concentrated H2SO4: role of catalyst and water absorbing agent.4, the use of acetic acidAcetic acid ...
The combined Na2CO3 fractions were acidified to pH 1-2 with concentrated HCl and the resulting precipitate was collected by filtration and oven dried to obtain the required acids.24General procedure: Equimolar quantities of 2-chloro acetic acid/3-chloro propionicacid (0.05 mol) and appropriate ...
the residual liquid is cooled and filtered to remove acetamide, sodium chloride solids, after washing with 1% Na2CO3 solution and layering, the oil layer is distilled under reduced pressure, toluene is distilled out first, and then the 88-98 ℃/0.07MPa fraction is collected as triethyl orthoaceta...

Acetic acid is a colorless transparent liquid with pungent sour odor. It is also known as Glacial acetic acid whenever the purity is 99.8% min. Acetic acid, also called GAA, is the main component of vinegar. After solidification, it becomes a colorles...
鉴于湿生物质如食品加工工业残余物和城市污泥中含有大量蛋白质的情况,以氨基乙酸作为蛋白质的模型化合物进行超临界水气化实验,研究了反应温度和反应时间耦合条件下Na2CO3的催化特性以及氨基乙酸气化产物特性。 更多例句>> 4) Amino acetic acid 氨基乙酸 1.
In this study, para-chlorophenoxyacetic acid (P-CPA) was selected as a CPA herbicidal pollutant to be removed from synthetic wastewater by adsorption using activated carbon prepared from pine cones by alkaline chemical activation. Cone wood can be used as a precursor (Pine Cone Precursor, designa...
