Participants

Reaction Steps

96 g of ion exchange water and 96 g (2.4 moles) of sodium hydroxide were added to a 1 L four-necked separable flask equipped with a stirrer, a reflux condenser and a dropping funnel to dissolve the sodium hydroxide in the ion exchange water. 68.4 g (0.2 moles) of sucrose was further added, and reacted at 80° C. for 90 minutes while stirring to obtain an alkaline sucrose aqueous solution. 290 g (2.4 moles) of allyl bromide was added dropwise into the alkaline sucrose aqueous solution for 2 hours while controlling rapid heating caused by an etherification reaction. Thereafter, the etherification reaction was completed by aging the reaction solution at 80° C. for 3 hours. After cooling, 400 g of ion exchange water was added to the reaction solution taken from the separable flask, and unwanted water-soluble components were removed from the oils to obtain crude oil-soluble sucrose allyl ether. Subsequently, 250 g of ion exchange water was added, and volatile components formed as the by-products were distilled off together with water using a rotary evaporator. 120 g of n-hexane and 40 g of ion exchange water were further added, and water-soluble impurities were removed again through liquid separation. The n-hexane was distilled off from the separated oily phase using a rotary evaporator to obtain 110 g of purified oil-soluble sucrose allyl ether. The etherification degree of the oil-soluble sucrose allyl ether was 6.5.
