| titleOfInvention | Alkylation of aromatic hydrocarbons by borate esters |
| abstract | The alkylation of an aromatic hydrocarbon is effected with an aliphatic borate in the presence of sulphuric or hydrofluoric acid containing not more than 10% weight of water. The aliphatic groups in the borate may contain 2-25 carbon atoms derived from paraffins, particularly n-paraffins, or cycloparaffins and the borate may be of the formula (RO)3B, (ROBO)3 or (RO)2-BOB(OR)2 or any mixture thereof, the R groups being hydrogen or alkyl with at least one being alkyl. Mixtures obtained by the oxidation of a paraffin in the presence of boric acid or boric oxide may be used. The aromatic hydrocarbon may contain up to 18 carbons and three fused ring, preferably benzene, and is used in a mol. ratio to alkoxy group in the borate of 4-50:1. The amount of acid catalyst may be 5-100 equivalents per equivalent of alkoxy groups in the borate. Reaction is effected for 1/2 -6 hours at 0-100 DEG C. In the examples dodecyl benzene is obtained from benzene and the product of oxidizing dodecane in the presence of boric oxide.ALSO:Mixtures of boron compounds containing mono-, di- and tri-alkyl borates, alkoxy boroximes and alkyl pyroborates are obtained by oxidizing a paraffin in the presence of boric acid or boric oxide. In an example, n-dodecane is oxidized with air at 170 DEG C. in the presence of boric oxide to obtain borate esters. |
