Fluoroethene (FE) is a stable molecule in aqueous solution and its aerobic transformation potentially yields F-. This work evaluated if FE is a suitable surrogate for monitoring aerobic vinyl chloride (VC) utilization or cometabolic transformation. Experiments were carried out with three isolates, Mycobacterium strain EE13a, Mycobacterium strain JS60, and Nocardioides strain JS614 to evaluate i...

This paper investigates distribution behaviour of the carcinogenic compound vinyl chloride (VC) under semi-natural conditions in a three-phase system (air, water, and aquifer material). A stainless steel column was fi lled with quaternary aquifer material (gritty sand) from a contaminated site (Bitterfeld, Germany). VCcontaminated water with a defi ned concentration was prepared and pumped in s...

A patient who worked with polyvinyl chloride developed a malignant haemangioendothelioma of a toe. This rare tumour is more commonly found in the liver where it has been reported to arise in association with exposure to the vinyl chloride monomer.

An investigation of the natural products chemistry of the brown alga Sargassum asperifolium from the red sea yielded a new steroidal metabolite, 24-vinyl cholest-4-ene-24-ol-3-one, saringosterone (3), a known steroidal metabolite, 24-vinyl cholest-5-ene-3b,24-diol, saringosterol (4), and known diterpene with a hydroazulene skeleton, dictyone (1). The identification of the isolated metabolites w...

Novel LaOCl/LaCl3 catalysts have been discovered that enable the production of vinyl chloride monomer from ethane. An ethane-based process would result in both capital savings and raw materials savings when compared to the current most effective vinyl technology. These materials are unique in the world of chlorination/oxychlorination as the mechanism for chlorination over LaOCl/LaCl3 occurs on ...

Abstract. Flexible free standing polymer electrolyte films have been successfully prepared using a blend of poly(vinylidene fluoride-co-hexafluoropropylene) (PVDF-HFP) and poly(vinyl chloride) (PVC) doped with lithium perchlorate (LiClO4). The conductivity of the film was influenced by salt concentration and the degree of crystallinity. An optimum room temperature conductivity obtained was 2.10...

In the title compound, trans-[RhCl(C(20)H(17)P)(2)(CO)], the Rh(I) atom is situated on a center of symmetry, resulting in a statistical 1:1 disorder of the chloride [Rh-Cl = 2.383 (2) Å] and carbonyl [Rh-C = 1.752 (7) Å] ligands. The distorted trans square-planar environment is completed by two P atoms [Rh-P = 2.3251 (4) Å] from two diphen-yl(4-vinyl-phen-yl)phosphane ligands. The vinyl group i...

A Multi-objective optimization procedure has been developed to determine some kinetic parameters of free radical polymerization of vinyl acetate based on genetic algorithm. For this purpose, mathematical modeling of free radical polymerization of vinyl acetate is carried out first and then selected kinetic parameters are optimized by minimizing objective functions defined from comparing exp...
