  • Chemical mutagenicity is a major hazard that is important to workers' health. Despite the use of large amounts of allyl chloride, the available mutagenicity data for this chemical remains controversial. To clarify the mutagenicity of allyl chloride and because a micronucleus (MN) test had not yet been conducted, we screened for MN induction by using male ICR mice bone marrow cells. The test results indicated that this chemical is not mutagenic under the test conditions. In this paper, the regulatory test battery and several assay combinations used to determine the genotoxic potential of chemicals in the workplace have been described. Further application of these assays may prove useful in future development strategies of hazard evaluations of industrial chemicals. This study also should help to improve the testing of this chemical by commonly used mutagenicity testing methods and investigations on the underlying mechanisms and could be applicable for workers' health.

  • The synthesis of epichlorohydrin was carried out by the epoxidation of allyl chloride with tert-butyl hydroperoxide(TBHP) over silica supported molybdenum catalyst. Kinetic study was performed at $60-80^{\circ}C$ and 10 atm with the molar ratio of TBHP/Allyl chloride between 0.01 and 0.1 in a batch reactor. The epoxidation of allyl chloride was inhibited by tert-butyl alcohol and kinetic data could be represented by Michaelis-Meten type rate equation. The reaction mechanism could be explained by the combination of reversible adsorption of TBHP and tert-butyl alcohol accompanied by reaction of allyl chloride with TBHP adsorbed on $Mo/SiO_2$ catalyst.

  • Complex permittivity spectra of Allyl Chloride (AC), 2-Butanone (2-BU) and their binary mixtures over the entire range of concentration were obtained using the Time Domain Reflectometry (TDR) technique in microwave frequency range at various temperatures. Static dielectric constant and relaxation time are obtained from complex permittivity spectra. Density ($\rho$) and refractive index ($n_D$) are also measured. These parameters are used to determine excess dielectric constant, excess inverse relaxation time, excess molar volume, excess molar refraction, polarity, Bruggeman factor and thermodynamic parameters viz. enthalpy of activation and entropy of activation. The values of static dielectric constant and relaxation time increases while density and refractive index decreases with the percentage of 2-Butanone in Allyl Chloride increases. Excess parameters were fitted to a Redlich-Kister equation.

  • Phosphates and phosphoric amides were synthesized by the reaction of phosphoryl chloride with allyl alcohol, 2,3-dibromopropanol, 2-pyrrolidone and ethylenimine. All of these compounds were thermally very unstable. Allyl phosphorodichoridate and diallyl phosphorochloridate gave significant amount of polymeric products when they were distilled. IR spectra showed characteristic P=O stretching bands between 1300 and $1200 cm^{-1}$ and NMR spectra were very complicated due to the long range coupling effect of phosphorus atom. And mass spectrum of 2,3-dibromopropyl phosphorodichloridate gave no indication of molecular ion peak.

  • The sixty nine chemicals that are closely linked to chemical accident are designated as the substances requiring preparation for accidents and managed for public health under the Toxic Chemicals Control Act. In this study, storage stability of allyl chloride (AC) and carbon disulfide (CD), which are highly inflammable and volatile in tedlar bags, was studied for gaseous chemicals sampling. Storage stability was studied considering storage temperature ($2^{\circ}C$, $25^{\circ}C$), chemical concentration (low conc. ppm, high conc. ppm) and storage time (0, 48, 96, and 144 hr). Also, the stability of bags containing one type of chemical substance and the bags containing a mixture of chemicals was compared against each other. As a result, two chemicals showed decreasing storage stability based on storage time. Also two chemicals presented statistical significance of concentration and mixing type.

  • Dielectric measurement on binary mixtures of Allyl chloride (ALC) with 2-Pentanone (2-PE) and 2-Hexanone (2-HE) has been carried out over the entire concentration range using Time Domain Reflectometry (TDR) technique at various temperatures in microwave frequency range of 10 MHz to 10 GHz. The static dielectric constant, excess static dielectric constant (${\varepsilon}^E_S$), effective Kirkwood correlation factor ($g^{eff}$) of binary mixtures over entire concentration range were determined to study the effect of increasing alkyl group of ketones on hetero molecular interaction. It was found that magnitude of excess static dielectric constant of mixtures increases with increase of alky group of ketones. The study reveals that the dipole moment of Allyl chloride in mixture have antiparallelism tendency where as 2-pentanone and 2-hexanone have parallelism tendency. Excess static dielectric constant is also fitted to Redlich-Kister equation to get information about rates of multimers formation.

  • Objectives: Chemical hazard evaluations are important for workers' health and working environments. Allyl chloride (CAS No. 107-05-1) is used in many industries, leading to concerns about the possibility of threats to the health of workers. Since only insufficient or controversial information is available about potential related hazards, an in vitro mammalian chromosomal aberration (CA) assay was conducted in order to gain additional information concerning any such hazards. Moreover, toxicological information from this study could be applied for workers' rights to know, and to prepare or update the Materials Safety Data Sheet (MSDS) for a number of industries. Methods and Results: The assay was performed using the Chinese hamster lung fibroblast cell (ATCC, CRL-1935), by the direct method (-S9) and by the metabolic activated method (+S9 mix). Using the direct method, the seven dosages in the 48-hour treatment group did not show that the frequency of CA is proportionate to the dosage. The frequency of CA is not proportionate to the dosage addition for a six-hour treatment using the metabolic activated method. Conclusions: From these findings, it was decided that this chemical does not induce chromosomal aberrations under the tested conditions.

  • The methods for improving epichlorohydrin process was investigated by carrying out experiments on hypochlorination reaction, from which dichlorohydrin is produced by reacting with allyl chloride and chlorine. As the recycle water from PVC plant was used instead of industrial water for reaction, the effect of recycle water on the reaction yield was studied. It was shown from this experiment that the recycle water rarely affected on the ratio between products. TCPA, which was almost of byproducts, could be removed before purification process using "extractant A". This could prevent additional side reaction by TCPA and reduced energy to separate it in purification part. The change of product yield was observed as the chlorine gas addition decreases which reacted with allyl chloride. It seems that the yield of major products didn't change almost, but the byproducts showed rather reduced trend with decreasing chlorine gas.
