Oxidative copolymerization of aniline with o- and p-toluidine by ammonium per sulfate: Kinetic and pathway
The kinetic study on the oxidation of aniline with oand p-methylaniline by ammonium persulfate (APS) has been carried out. The course of copolymerization was investigated by UV-vis spectroscopic method. Structural characterization was studied by FT-IR spectral analysis. The electronic spectra of the copolymers poly(aniline-co-p-toluidine) and poly(aniline-co-o-toluidine) show hypsochromic shift...
متن کاملIncreased bladder cancer risk among workers exposed to o-toluidine and aniline: a reanalysis.
INTRODUCTION In 1991, the US National Institute for Occupational Safety and Health (NIOSH) reported an increased bladder cancer risk in a cohort of 1749 workers potentially exposed to o-toluidine and aniline at a chemical manufacturing plant. As additional information showed that workers in certain departments had been misclassified regarding o-toluidine exposure, we therefore conducted a reana...
متن کاملN-(2-Pyridyl)-4-toluidine
There are two mol-ecules in the asymmetric unit of the title compound, C(12)H(12)N(2), with dihedral angles between the aromatic rings of 48.35 (12) and 51.02 (12)°. In the crystal structure, both mol-ecules form inversion dimers, linked by pairs of N-H⋯N hydrogen bonds.

ترانسفورماتورهای قدرت از اجزای اصلی شبکه تامین انرژی الکتریکی می باشند که عملکرد قابل اطمینان ترانسفورماتورها یکی از فاکتورهای مهم و تعیین کننده در تامین انرژی الکتریکی محسوب می شود. در نتیجه بررسی و مانیتور عملکرد ترانسفورماتورها در شبکه و همچنین عیب یابی این ترانسفورماتورها غیرقابل اجتناب و ضروری می باشد. به طور کلی عایق های مایع در صنعت فشار قوی کاربردهای متفاوتی دارند که مهمترین وظیفه آنها...
15 صفحه اولp-Chloro-o-toluidine and its hydrochloride.
There is limited evidence for the carcinogenicity of p‐chloro-o-toluidine from epidemiological studies in humans. Three cohort studies found high relative risks for urinary-bladder cancer among workers exposed to p-chloro-o-toluidine; however, confounding by coexposure to other potential urinary-bladder carcinogens could not be ruled out. Documented human exposure to p‐chloro-o-toluidine has oc...
