With sodium hydroxide; benzenesulfonic acid; | Preparation of 4-methylenetetrahydropyran I To a mixture of 348 g (3 moles) of 3-methylpentane-1,5-diol, 2,670 g of 30% w/w caustic soda ( 20 moles of NaOH) and 100 ml of an organic solvent there were added, at reflux temperature T C. and over a period of 1 hour, 635 g (3.6 moles) of benzenesulfonic acid, after which the mixture was kept at T C. for a further 15 minutes before the reaction mixture was worked up to obtain the 4-methylenetetrahydropyran as a hetero-azeotrope with water. Details of the tests and their results are listed in the Table below. |
