萘乙酸是人们根据天然激素的化学构造,人工模拟合成的一种植物生长刺激素.具有结构简单、人工合成容易、生产成本低廉、适用范围广泛、操作方便易行、使用效果显著等优点,因此在农、林业生产及园林花木上,被广泛应用.萘乙酸的化学性质萘乙酸(NAA)具有生理活性的化学名称叫α—萘乙酸,为白色结晶,无臭,难溶于水,易溶于氨水、乙酸、酮、醚、醋酸和苯.一般市售萘乙酸晶体粉剂中,含有微量的β—萘乙酸、萘二乙酸及其它无生理活性的物质.产品因其杂质含量的增加,则粉剂的颜色随之加深为灰黄色、灰棕色等等.目前市场上出售的商品还有20—70%的萘乙酸铵、萘乙酸钠盐等粉剂、液剂和萘乙酸甲脂油剂等,这些均可直接加水稀释后用,不必加其它溶剂预溶.
Naphthylacetic acid is a kind of plant growth-stimulating hormone synthesized by artificial chemical synthesis according to the chemical structure of natural hormone, has the advantages of simple structure, easy synthesis, low production cost, wide range of application, convenient and easy operation, remarkable effect of use and the like In agriculture, forestry production and garden flowers and trees are widely used.Naphthalene acetic acid chemical properties naphthaleneacetic acid (NAA) with physiological activity of the chemical name is α-naphthalene acetic acid, white crystal, odorless, insoluble in water, soluble In ammonia, acetic acid, ketones, ethers, acetic acid and benzene.General commercial naphthalene acetic acid crystal powder contains a small amount of β-naphthalene acetic acid, naphthalene diacetic acid and other non-physiological activity of the product because of its increased content of impurities, then The color of the powder is deepened to be greyish-yellow, gray-brown, etc. There are still 20-70% of ammonium naphthalene acetate, sodium naphthalene acetate and other powders, liquid and nail polish in the market, etc. Can be diluted directly with water, without having to add other solvents to dissolve.
