Gas emissions from ceramic kilns can contain variable quantities of HF, HCl and SO{sub}2, depending on the raw materials and type of fuel involved. The present work addressed the chemical reaction kinetics of these compounds with NaHCO{sub}3 powder. The study was conducted at an industrial ...
去除有机层,在0-5°C下用10%KHSO4将水层酸化至pH 2.0,并用乙酸乙酯(2 x 10 mL)萃取。合并的有机层用5%NaHCO3溶液、水、盐水洗涤,并用无水Na2SO4干燥。浓缩乙酸乙酯层,残余物从EtOAc/正己烷(2:8)混合物中结晶,得到白色固体产物BOC-L-亮氨酸(1.53g,95%收率)[3]。 图四BOC-L-亮氨酸的合成3 参考...
