Versuchsvorschrift
In 260 ml of ethanol were dissolved 33.37 g of the 2'-hydroxy-4',6'-bis(methoxymethoxy)acetophenone obtained in Production Example 11 and 32.20 g of the 3,4-bis(methoxymethoxy)benzaldehyde obtained in Production Example 24, and 300 ml of a saturated solution of potassium hydroxide in ethanol was added to the solution and the mixture was stirred for 24 hours to effect a reaction. After the reaction, the pH value of the reaction liquid was adjusted to about 6 by 6 N hydrochloric acid, and the formed precipitate was recovered by filtration, washed with water and dried to obtain 53.17 g (yield=87.9%) of 2'-hydroxy-3,4,4',6'-tetrakis(methoxymethoxy)chalcone.
