Brief Introduction

Phosgene, viewed from the chemical structure, is a diacyl chloride derivative of carbonic acid. It is a very active electrophilic reagent and easy to hydrolyze. It is a severe asphyxiating toxic gas. Inhalation of high concentration can cause pulmonary edema. The toxicity is about 10 times greater than that of chlorine, but it has no accumulation effect in the body. Its common name is translated from Greek φως (light) + Γίνει (generated). Phosgene was originally produced by the decomposition of chloroform by light, so it has this name.

Brief Introduction

Triphenyl (also known as diphenylbenzene or biphenyl) is a kind of closely related aromatic hydrocarbons, which is composed of central benzene ring and two phenyl substituents. There are three isomers: o-triphenyl, m-triphenyl and p-triphenyl. Commercial cascaded triphenyls are generally mixtures of three isomers, which are used to produce polychlorinated biphenyls. PCTs were previously used as heat storage and transfer agents. P-terphenyl is the most common of the three isomers, which is used as raw material for dye laser and sunscreen.
