a mineral acid with many industrial uses; commonly used in the laboratory preparation of hydrogen halides Phosphorus pentachloride: one of the most important phosphorus chlorides; a chlorinating reagent. Also used as a dehydrating agent for oximes which turn them into nitriles. Phosphorus tribromide: used for the conversion of alcohols to alkyl ...
Linear alkylbenzenes (sometimes also known as LABs) are a family of organic compounds with the formula C 6 H 5 C n H 2n+1. Typically, n lies between 10 and 16, although generally supplied as a tighter cut, such as C 12 -C 15 , C 12 -C 13 and C 10 -C 13 , for detergent use. [ 1 ]
It is the raw material in the production of synthetic sulfonate detergents, which are found in a variety of household products such as soap, shampoo, toothpaste, laundry detergent, etc. Linear alkylbenzenes (LAB) and branched alkylbenzenes (BAB) are families of alkylbenzene used to prepare synthetic sulfonates. However, LABs are more ...
Benzene targets the liver, kidney, lung, heart and brain and can cause DNA strand breaks and chromosomal damage, hence is teratogenic and mutagenic. Benzene causes cancer in animals including humans. Benzene has been shown to cause cancer in both sexes of multiple species of laboratory animals exposed via various routes. [83] [84]
It is dangerous to try to dispose of benzene by washing it down a sink, since it is toxic, will cause environmental damage and presents a fire risk. It is probable that trying to dispose of benzene in this way will also break local environmental rules. Instead, retain in a safe place in the laboratory (well away from any source of ignition)

price of food may account for some, but probably not all, of the increase in calories consumed as prices dropped. They propose a model of self-control based on hyperbolic discounting to explain why the increased availability of easy-to-consume snack foods has had a disproportionate effect on weight gain compared to other foods.
The other principal route is by the oxidative dehydrogenation of benzene: 2 C 6 H 6 + ½ O 2 → C 6 H 5 −C 6 H 5 + H 2 O. Annually 40,000,000 kg are produced by these routes. [9] In the laboratory, biphenyl can also be synthesized by treating phenylmagnesium bromide with copper(II) salts. It can also be prepared using diazonium salts.
