2-Propenoic acid, 3-phenyl- → Sodium;3-phenylprop-2-enoate

Participants

Reaction Steps

In 300 ml of purified water, 1.64 g of sodium hydroxide was dissolved. In the resultant aqueous solution, 6.06 g of cinnamic acid (purity 99.9%, conjugate number 4) was throughly dissolved while under stirring, to produce a sodium cinnamate aqueous solution. To this aqueous solution, a europium chloride aqueous solution obtained in advance by thoroughly dissolving 5.0 g of europium chloride (EuCl3.6H2O; purity 99.99%) in 100 ml of purified water was gradually added at room temperature while under stirring. During the reaction, the pH value of the reaction solution was adjusted to a varying value indicated in Table 2. Then, it was subjected to continued thorough stirring and thereafter subjected to filtration. Then, the separated reaction product was thoroughly washed with 500 ml of purified water and dried in vacuo at 80° to 100° C. for 20 to 24 hours. Consequently, the products indicated in Table 2 were obtained.
