α-萘乙酸是一种优良的植物生长刺激素,性质安定,不易发生药害,对植物的抽条生根,促进和延迟果树芽的开放,提高植物单位的产量,均有一定的实际用途。随着农业的大跃进,α-萘乙酸是值得介绍的一个品种。α-萘乙酸为白色结晶或结晶性粉末,无嗅,熔点为131—133℃。在水中的溶解度不大,75℃时在100毫升中溶解41—42毫克,在热水、乙醚、苯中则易溶解。它的钾盐或钠盐极易溶于水中,使用很为方便。现将试制情况介绍如下。 1.反应:
Alpha-naphthalene acetic acid is an excellent plant growth hormone, stable in nature, not prone to phytotoxicity, the rooting of plants, and promote and delay the opening of fruit trees buds, improve the yield of plant units, have some practical use. With the great leap forward in agriculture, alpha-naphthalene acetic acid is a species worth introducing. α-naphthalene acetic acid as a white crystalline or crystalline powder, odorless, melting point of 131-133 ℃. Solubility in water is not large, dissolved in 75 ml 100 ml 41-42 mg, soluble in hot water, ether, benzene. Its potassium salt or sodium salt is very soluble in water, very easy to use. Trial production is introduced below. Reaction
