Tenders are invited for Boron trichloride
gas with cylinder
It detects all the chemical agents the military requires--nerve, blood and blister--and toxic industrial chemicals such as ammonia, boron trichloride
, phosgene, nitric acid, sulfur dioxide and hydrogen cyanide.
Boron trichloride in 1 M (mol [L.sup.-1]) toluene solution was purchased from Beijing Multi Technology, and used without further purification.
20 mL (0.04 M) boron trichloride in 1 M-toluene solution was introduced with a syringe and injected into a dropping funnel.
As described in Scheme lb, the synthesis route developed in the study is based on the polycondense between two types of groups: the amine group of p-phenylene diamine and the chlorine atom of the boron trichloride. In general, high solution concentration and longer reaction time lead to high molecular weight products.
Formulations have been developed for neutralizing malathion, hydrogen cyanide, sodium cyanide, butyl isocyanate, carbon disulfide, phosgene gas, capsaicin in commercial pepper spray, chlorine gas, anhydrous ammonia gas; hydrogen sulfide, sulfur dioxide, formaldehyde, ethylene oxide, methyl bromide, boron trichloride
, fluorine, tetraethyl pyrophosphate, phosphorous trichloride, arsine, and tungsten hexafluoride.
BOC Gases will work with Twin-Star in satisfying all cylinder gases such as tungsten hexaflouride, etching gases such as halocarbon 116 and boron trichloride
, and dopants including phosphine mixtures.
The hydride canister treats such gases as arsine, phosphine, diborane, silane, and organometallics, while the etch-gas canister treats boron trichloride
, hydrogen chloride, hydrogen fluoride, dichlorosilane, tetrachlorosilane, and tungsten hexafluoride.
Tenders are invited for Gas cabinets for boron trichloride
sulphur hexa fluoride gases
Treatment of boron trichloride
with the anion of the bulky phosphinimide tert-[Bu.sub.3]P=NLi causes loss of [Cl.sup.-] to make a new B-N bond.
GaAs can be etched with a mixture of an inert gas, such as argon, and a reactive gas, such as chlorine or boron trichloride
. The reactive gas etches the GaAs by forming volatile reaction products.
