Versuchsvorschrift

CH3CHClCOOH (50 g) and CH2═CHCH2CH2OH (75 ml) were put into a flask, and 10 ml of concentrated sulfuric acid was added dropwise, followed by stirring at room temperature for 10 minutes. The reaction solution was poured into 250 ml of a saturated sodium carbonate aqueous solution. 150 ml of water and 150 ml of t-butylmethyl ether were added for liquid separation to obtain a t-butylmethyl ether layer as an organic layer. The organic layer was washed with 150 ml of water, dried over magnesium sulfate and then subjected to filtration to obtain a crude liquid. The crude liquid was concentrated to obtain CH3CHClCOOCH2CH2CH═CH2.
