Fundamentals of Hydrolysis: Kinetics of Carbaryl Hydrolysis

چکیده

Introduction: During 2000, 293 billion pounds of about 8000 different organic compounds were manufactured in the United States (1). Many millions of pounds of synthetic organic compounds are deliberately introduced into the environment for weed and pest control, and many millions of pounds of other chemicals are introduced into the environment through their proper uses. However, an increase in production and dispersion of synthetic organic chemicals is reported to be responsible for species extinction and several hundred thousand of human cancers per year (2). Several years ago, the government began to regulate the manufacture and use of selected chemicals, such as DDT, which had been shown to be exceptionally hazardous to the biological environment (3). In addition, federal registrations such as the Toxic Substance Control Act regulate the introduction of hazardous chemicals into the environment (3).

THE KINETICS OF HYDROLYSIS OF TRANS-DIFLUOROTETRAMMINECHROMIUM (111) ION IN VARIOUS CONCENTRATED ACID SOLUTIONS

The rate of hydrolysis of trans -[Cr(NH ) F ] was obtained as a function of acid concentsation in perchloric, sulfuric and nitric acid at 3Q°C. The results have been analyzed by the treatment of Bunnett and Olsen. Values of the parameter ?in Olsen equation are consistent with the participation of water as a proton-wansfer agent in the rate-determining step. The Arrhenius plot for perchlori...

Hydrolysis of semi mustard (S.M) by MnCo2O4 (MnO-Co2O3) nanocomposite as a binary oxide catalyst: kinetics reactions study

MnCo2O4 (MnO-Co2O3) nanocomposite as a binary oxide has been successfully prepared by precipitation method using cobalt nitrate and manganese nitrate as the precursors and then characterized by scanning electron microscopy-energy dispersive micro-analysis (SEM-EDX) and X-ray diffraction (XRD) techniques. In this work, we report the hydrolysis kinetics reactions of semi mustard (chloroethyl ethy...

Kinetics of carbon dioxide, methane and hydrolysis in co-digestion of food and vegetable wastes

Kinetic models which can express the behaviors of hydrolysis and biogas generation more precisely than the conventional models were developed. The developed models were evaluated based on the experimental data of six batch reactors. Anaerobic digestion test was co-digestion of food and vegetable waste with inoculating horse dung by 15% of the total wet weight, at the temperature of 37o</su...

A Simple Method for Partial Purification of Reference Clays

ÐThe influence of clay preparation procedure on sorption and hydrolysis of carbaryl (1-naphthyl, N-methyl carbamate) by the reference smectite SWy-2 was examined. For research purposes, reference clays are sometimes used without purification, or more commonly, the <2 mm size fraction is obtained by gravity sedimentation or low-speed centrifugation. We determined that these common methods did no...
