    摘要： 2-Phenyl-1.2.3-triazole-4-carboxaldehydes having the formula: ##STR1##are obtained by oxidizing a 2-phenylglycosotriazole having the formula: ##STR2## wherein R is hydrogen, halogen, methyl, carboxyl, a sulfonic acid group or the alkali metal salt thereof, n is 2 or 3, R' is hydroxymethyl when n is 2 and is hydroxymethyl or methyl when n is 3, with an oxide of manganese such as manganese dioxide or manganese oxide in dilute sulfuric acid of 20 to 80 wt. % concentration at a temperature of 0.degree. to 80.degree. C. The oxidation reaction is carried out in a dispersed state for from 2 to 100 hours and the resultant aldehyde is separated from the reaction mixture by extraction with an organic solvent. The purity of the aldehyde thus obtained is higher than 85 wt. % and the yield is 40% to quantitative on the basis of 2-phenylglycosotriazole. The aldehyde can be further purified by convenient means.

    摘要： Novel chlorinated 4-methylphthalic acids or anhydrides of the general formula ##STR1## wherein n is an integer of 1, 2 or 3, with the proviso that when n is 1, the chlorine atom is positioned at 3- or 5-position and when n is 2, the chlorine atoms are positioned at 3- and 5-positions. The new compounds are produced by dissolving 4-methylphthalic anhydride in concentrated sulfuric acid or fuming sulfuric acid to form a solution, and reacting the solution with chlorine at room temperature preferably in the presence of a catalytic amount of iodine, thereby to yield a crude product containing a mixture of chlorinated 4-methylphthalic acids. By subjecting the mixture to a thermal dehydration treatment in an inactive organic solvent, each of the chlorinated compounds may be isolated as its corresponding anhydride in the form of crystals.These chlorinated 4-methylphthalic anhydrides are valuable as intermediates for the preparation of dyestuffs or pigments.
