Oxalic acid, or oxalic acid, is one of the simplest organic dibasic acids. It is generally a colorless and transparent crystal, which is harmful to the human body. It will cause the pH in the human body to lose its balance and affect the develop...
PROCESS FOR THE SYNTHESIS OF CATIONIC SURFACTANTS OBTAINED FROM THE CONDENSATION OF FATTY ACIDS WITH ESTERIFIED DIBASIC AMINOACIDS, AND THEIR APPLICATION AS ANTIMICROBIAL AGENTS The process comprises a first step of esterification of an aminoacid and is characterized by a second step of condensation of...
SK Gumtyaa,SC Lahiria 摘要: The solvent effects on the dissociation of the simplest dibasic organic acid were examined from the determi nation or the first and second dissociation constants of oxalic acid conductometrically and pH-metrically In water + 2-propanol mixtures (0-87 wt% of 2-...
