4-Bromo-anisole prodn. from anisole - by reaction with bromine dissolved in aq. hydrobromic acidProdn. of p-bromoanisole (I) comprises reacting anisole (II) with a soln. of Br2 in aq. HBr. Pref. Br2 is dissolved in 25-62 wt.% HBr to give a soln. with Br2:HBr soln. wt. ratio...
Dibromoanisol‚ was prepared in a yield of 52% with a melting point of 55-58 C . Reaction: Mechanism: Procedure:Anisole(0.35mL‚ 0.0378mol) was obtained and placed in a pre-weighed 25 mL round bottom flask‚ along with 2.5 mL of glacial acetic acid and a magnetic stir bar. ...
Thus the alkylene polyamines obtained from the reaction of 2 to 11 moles of ammonia with 1 to 10 moles of dichloroalkanes having 2 to 6 carbon atoms and the chlorines on different carbons are suitable alkylene polyamine reactants.Aldehyde reactants useful in the preparation of the high ...
The alkylation reaction can be carried out with solid catalysts such as WOx/ZrO2, acid clay, zeolites and ion-exchange resin catalysts. Preferably, the olefin feed is slowly added to a mixture of anisole and catalyst to minimize the formation of olefin oligomers. The viscometric property of the...
This comparative system was based on the cyclic voltammetric measurement of a reaction cell, where the total current amplitude was associated with the quantitative interaction between the working electrode and the analyte (2,4,6-TCA) itself. 2. Materials and Methods 2.1. Reagents 2,4,6-Trichloro...
