Effects of ethanol on the kinetics of methyl ethyl ketone in man.

طراحی و توسعه یک تله سوزنی مبتنی بر جاذب PDMS جهت ریزاستخراج تولوئن و متیل اتیل کتون از نمونه های آبی به روش فضای فوقانی دینامیک

Introduction: Due to the widespread use of toxic chemicals in most workplaces that can lead to toxic effects on human, various chemical extraction technique have been defined for analysis these toxic substances in air, water and biological samples. The purpose of this research is extraction of  toluene and methyl ethyl ketone from aquatic samples with needle trap device and  one co...

استخراج تولوئن و متیل اتیل کتون از نمونه‌های آبی به روش به‌دام‌اندازی توسط سوزن و جاذب سنتز شده بر پایه ترکیبات نانو

Background and Aims:Nowadays, many different techniques to extraction of chemical compounds from aquatic  samples have been introduced, for examples techniques based on the use of needles that were packed with some sorbents. Considering that so far no synthesis sorbent based on single-walled carbon nanotubes and sol-gel techniques for the extraction of toluene and methyl ethyl ketone from ...

Abatement of Benzyl Alcohol and Methyl Ethyl Ketone (MEK) from Polluted Air Over Nanostructured Mn -Supported Alumina Catalyst

Biological monitoring of petrochemical industry workers exposed to benzene, toluene, xylenes, methyl ethyl ketone, and phenol in Southern Iran

Background: Volatile organic compounds (VOCs), including carcinogens and toxic compounds, are produced in petrochemical industries. We undertook this study in order to study workers’ respiratory exposure to different VOC concentrations and compare the results with the urinary levels of its metabolites and study the correlation between them in petrochemical industries. Materials and Met...

Modeling and Simulation a Catalytic Fixed Bed Reactor to Produce Ethyl Benzene from Ethanol

Ethyl benzene used increasingly each year is the raw material of producing styrene monomer. This substanceis produced from benzene alkylation with ethylene or ethanol, depending on the availability and cost of rawmaterials. In this study benzene alkylation in the presence of ethanol in a catalytic fixed bed reactor inthree states of isotherm, adiabatic and non-isotherm-non-adiabatic is mathemat...
