An antibacterial liquid hand cleaning composition with desirable cleansing properties to the human skin comprising a C 8-18 ethoxylated alkyl ether sulfate anionic surfactant, a betaine surfactant, a hydroxy containing organic acid and water.Anne Jacques...
The invention relates to a method for preparing ortho-hydroxybenzoic acid by catalyzing and oxidizing ortho-nitrotoluene with a metalloporphyrin and metal salt compound as a catalyst. The method comprises the following steps of: introducing the oxygen of 0.5-2.5Mpa into the aqueous ethanol of 0.5-...
All the conformers of ortho-hydroxybenzoic acid and diortho-hydroxybenzoic acid were studied by the CNDO/2 method. The results obtained confirm the experimental facts with respect to the strength of the intramolecular hydrogen bonds in these acids as well as in their anions....
In a typical process the acid (e.g. sali-cyclic acid) and 1-6 wt.% acid catalyst (H2SO4, benzene sulphonic acid, toluene sulphonic acid etc.) are mixed with excess amt. of alcohol e.g. methanol, ethanol, propanol, n-butanol, isobutanol etc. and the mixt. heated to 80-200 ...
