四乙基氢氧化铵合成路线

四乙基氢氧化铵上下游产品

四乙基氢氧化铵上游产品

四乙基氢氧化铵下游产品

四乙基氢氧化铵制备

1.先用甲醇溶解四乙基氯化铵，然后加入理论量的氢氧化钾-甲醇溶液，充分混匀，即有氯化钾析出：

当反应完全后，静置，减压过滤，所得滤液加入水进行减压蒸馏，除去醇和水，使溶液中四乙基氢氧化铵含量达44%，再于真空下干燥，所得结晶即为成品。
2.先用水溶解四乙基碘化铵，使之成为15%的溶液，然后加入理论量的氧化银，水浴加热并保温使反应完全：

滤去碘化银，所得洁净滤液即为成品。

Extracellular quaternary ammonium blockade of transient receptor potential vanilloid subtype 1 channels expressed in Xenopus laevis oocytes.

Mol. Pharmacol. 82(6) , 1129-35, (2012)

Transient receptor potential vanilloid subtype 1 (TRPV1) channels are essential nociceptive integrators in primary afferent neurons. These nonselective cation channels are inhibited by local anestheti...

Remarkably regioselective deacylation of cellulose esters using tetraalkylammonium salts of the strongly basic hydroxide ion.

Carbohydr. Polym. 111 , 25-32, (2014)

Tetraalkylammonium hydroxides have been found to mediate regioselective deacylation of cellulose esters. This deacylation surprisingly shows substantial selectivity for the removal of the acyl groups ...
