The utility model relates to a reactor in regular structure for continuously preparing cane sugar-6- acetic acid ester. The reactor comprises a reactor shell body, an upper seal head, a lower seal head, a catalyst in regular structure and a card, wherein a heat insulation jacket is arranged...
Other Methods of Preparing Acetic Acid Some naphthalene salts of cobalt, chromium, and manganese can be employed as metal catalysts in the oxidation of acetaldehyde. The chemical equation for this reaction can be written as: O2+ 2CH3CHO → 2CH3COOH ...
The authors have investigated the electric properties of trimethylacetic acid in the liquid and solid states. From the markedly small values of dielectric constant and conductivity, combined with the results of the X-ray investigation, it is proposed that the crystal of the room temperature phase ...
The synthesis of acetic acid and acetic anhydride. The manufacturing of resins, dyes, and art supplies. The production of fragrances in perfumes. It is used as a food flavoring and preservative. What is the common name for acetaldehyde?
This shift in the rotational preferences of the -CH 2 COOH moiety may be one of the reasons for the reduced plant-growth promoting activity of 2-alkyl-IAAs. 展开 关键词: 2-Ethylindole-3-acetic acid 2-Propylindole-3-acetic acid Auxin Conformational analysis Indole-3-acetic acid X-ray ...

Oligosaccharides were prepared by mild acid hydrolysis in 1% acetic acid at 100 °C for 1 h. The resulting disaccharide was purified by gel filtration on Bio-Gel P-2 in 0.1 M ammonium acetate and subsequent paper electrophoresis in pyridine acetate, pH 5.4. K15 was oxidized with excess sodiu...
The role of the molecular structure - different functional groups, the length of the carbon chain and the relative positions of different functional groups – of several complexing/chelating agents (acetic acid, glycine, ethylene diamine, succinic acid, alanine and amino butyric acid (ABA)) in con...
