摘要
以新鲜竹材为原料,经炭化和磺化制得的竹炭磺酸催化各种芳醛、芳胺和亚膦酸二乙酯一锅三组分合成α-氨基膦酸酯.结果表明:该固体酸具有催化性能好、操作简便、来源广泛和可重复利用等优点.
By using fresh bamboo condensation raw material,bamboo char sulfonic acid was obtained via sulfuric acid char-ring and sulfonation,which catalyzed the one-pot three-component synthesis of α-amino phosphonates by condensation of various aromatic aldehydes with aromatic amines and diethyl phosphite.Experimental results have shown that bamboo char sulfonic acids have advantages of high activity,simplicity of operation,wide range of sources and easy recycle.
