This technology greatly reduces the cost, particularly the employing of chloroacetic acid instead of dimethyl sulfate in the methylation process makes considerable contributions to environment protection.

Non-carcinogenic dye intermediate 2′-methyl-4,5′-diaminobenzene sulfonanilide(Ⅳ) was synthesized from p-methylaniline and p-aminoacetanilide by acetylation,chlorosulfonation,amidation and deacetylation.

his paper states the prepatation andelectrochemical response characteristics of the poly( p-methylaniline)film modified Pt electrode as a potentialsensor,A good linear relationship between themodified electrode potential and pH is obtained in therange of pH2～13.

Synthesis and Characterization of Spirocyclic Pentaerythritol p-cresol Ester of Phosphoric Acid;

The p-tolyl benzyl ether was synthesized by reaction of p-cresol and benzyl chloride in 95% ethanol as solvent and under microwave irradiation.

p-Cresyl phenylacetate was synthesized from p-cresol and phenylacetyl chloride by direct esterifica-tion using a conditional test.

Compared with Amberlite XAD-4,new polymeric adsorbent modified with acetylaniline(ZH-05) was prepared and used for adsorbing 4-methylaniline in aqueous solution,including the static equilibrium adsorption and desorption characteristics at different temperature,and the adsorption mechanism was further investigated.

The static adsorption and desorption performance for 4-methylaniline onto them and Amberlite XAD-4 at different temperature were studied and their adsorption mechanism were further investigated.

The adsorption capacities of new H and NK to 4-methylaniline are obviously much higher than that of Amberlite XAD-4,which is attributed to micropore mechanism and partial polarity.

We could receive the best reaction condition:p-toluidine ∶ammonium thiocanate ∶bromine is 1.
