✦ Synopsis

Abstmct-The

kinetics of absorption of 2-butene in aqueous solutions of sulphuric acid was studied in a stirred cell in the range of acid concentration from 70.2 per cent w/w (11.5 g mole/l.) to 80.2 per cent w/w (14.56 g mole/l.). The absorption was found to conform to fast pseudo-first order mechanism. The pseudo-first order reaction rate constant at 28°C was found to vary from about 500 to 3.8 X lo6 set+ over the above concentration range.

The absorption of 2-methyl-Z-butene (isoamylene) in aqueous solutions of sulphuric acid was also found to conform to fast pseudo-first order mechanism, in the range of acid concentration from 61.5 per cent w/w (9.395 g mole/l.) to 75 per cent w/w (12.845 g mole/l.). The pseudo-first order reaction rate constant at 30°C was found to vary from about 4.2 X lo5 to 2.2 X lo8 see-' over the above concentration range.
