据文献报导,交联毛细管柱的种类可分为Si—O—Si键型和Si—C—C—Si键型,后者多半使用辐射法、过氧化物法、偶氮化合物法引发交联反应。 在给定的温度下,过氧化物的氧含量在一定温度下损失一半所需要的时间,称为过氧化物的半寿命。异丙苯基过氧化物在135℃的半寿命为1小时。过氧化物在一定温度下分离出有一定的活性和一定数量的初级游离基。所谓活性是指初级游离基和单体加成的能力;所谓数量是指过氧化物释放游离基的速度。异丙苯基过氧化物的分解产物通常 According to the literature, the type of cross-linked capillary column can be divided into Si-O-Si bond type and Si-C-C-Si bond type, the latter mostly use radiation method, peroxide method, azo compound method to initiate crosslinking reaction. At a given temperature, the peroxide oxygen content at a certain temperature loss of half the time required, known as the half-life of peroxide. The half life of cumene peroxide at 135 ° C was 1 hour. Peroxide at a certain temperature isolated a certain activity and a certain amount of primary free radicals. The so-called activity refers to the primary radical and monomer addition capacity; the so-called number refers to the rate of peroxide release of free radicals. Cumene peroxide decomposition products are usually
