应用
Tetra-n-octylammonium bromide is associated with benzethonium chloride and used as a disinfectant, in surface treatment and preservative in hospitals and industries. It is used as a surfactant involved in the synthesis of blue-luminescent silicon nanoparticles in order to get uniform particle size. It is utilized as a cationic additive in the preparation of membranes using cyclam derivative 1,4,8,11-tetra(n-octyl)-1,4,8,11-tetraazacyclotetradecane as an ionphore and dibutyl phthalate as plasticizers.

备注
Hygroscopic. Incompatible with strong oxidizing agents.

产品说明

一般描述

四辛基溴化铵是一种有机表面包覆剂，常用于控制纳米颗粒合成过程中的尺寸和形状。

应用

以四辛基溴化铵 (TOAB) 为相转移剂，采用两相(有机-水相)烷基硫醇稳定的金纳米颗粒合成法，将四氯金酸金从水相转移到有机相。它还用于制备 TOAB 封端金纳米颗粒，与巯基封端纳米颗粒相比，显示出明确的等离子体吸收。
