Title: Alkylation of aromatic hydrocarbons by borate esters
IPC: C07C2/86
Filed: 1963-07-19
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.

Abstract: 655,760. Television. COLE, Ltd., E. K., and MARTIN, A. W. Nov. 16, 1948, No. 29695. [Class 40 (iii)] In a television receiver in which the video amplifier V1 supplies video signals from its anode circuit to the modulating grid of a cathode-ray picture reproducing tube T and in which synchronizing signals are derived from the video signals, in lead B, developed across a resistance in the cathode circuit of V1, video signals from the cathode circuit of V1 are also supplied, via C2, to the cathode of the tube T. With this arrangement the reduction in the signal developed at the anode of V due to the presence of the cathode load is compensated by the additional cathode modulation of the Tube T. If increased modulation of the cathode-ray beam is not required the anode load of V1 may be reduced, thus giving an improvement in the video characteristics of the circuit.
