Reaction of benzene with alcl3

WebThe facts. Benzene reacts with chlorine or bromine in an electrophilic substitution reaction, but only in the presence of a catalyst. The catalyst is either aluminium chloride (or aluminium bromide if you are reacting benzene with bromine) or iron. Strictly speaking iron isn't a catalyst, because it gets permanently changed during the reaction.

Any other chloroalkane would work similarly. If you want the Friedel-Crafts alkylation mechanism … WebThis page looks at the reaction of acyl chlorides (acid chlorides) with benzene in the presence of an aluminium chloride catalyst. This is known as a Friedel-Crafts acylation. Friedel-Crafts acylation of benzene Background and equations Acylation is the term given to substituting an acyl group such as CH 3 CO- into another molecule. WebJan 1, 1989 · The reactant mixture of benzene and 2-chloropropane was prepared by passing two dry nitrogen streams through individual benzene and 2-chloropropane evaporators and mixing the streams in a mixer. The flow-rate of 2-chloropropane was 1 mmol h and the benzene-to-2-chloropropane ratio was controlled in the range 0.9 to 4.1. builders merchants warrington area
