Optically active trans-1-( 4-alkylcyclohexyl) alcohols widely used in chiral liquid crystal materials were prepared via chemical resolution with commercially available chiral α-methylbenzylamine in excellent enantiomeric excess of 90% to> 99%. 用手性α苯乙胺为拆分剂通过化学拆分以较好的收率制备了可作为手性液晶材料的光学活性反式1(4烷基环己基)醇,光学纯度达90%~>99%。
The genotoxicity of sodium nitrite and N methylbenzylamine were detected. 作者研究观察了亚硝酸钠和N-甲基苄胺的遗传毒性作用。
The study on genotoxicity of sodium nitrite and N methylbenzylamine 亚硝酸钠和N-甲基苄胺的遗传毒性研究
The method is that methylbenzylamine can react with sodium nitroprusside in 20% acetaldehyde and NaHCO_3-Na_2CO_3buffer solution at 0 ℃ and form a stable and soluble blue compound. 该方法是用亚硝基铁氰化钠在20%乙醛和NaHCO3&Na2CO3缓冲液中,在0℃时与仲胺反应生成稳定而且可溶性的蓝色化合物。
