  Kinetics and mechanism of acid hydrolysis of peroxyketals

  摘要：

  The kinetics of hydrolysis of aliphatic ketone di-tert-butylperoxyketals R1R2C = O, R1, R2 = CH3, CH3; CH3, C2H5; CH3, n-C3H7; CH3, n-C6H13; CH3, i-C5H10; CH3, i-C4H9; C2H5, i-C3H7; n-C4H9, n-C4H9; CH3, C6H5-CH2, in dioxane in the presence of H2SO4 were investigated by IR spectroscopy. It was found that the reaction is reversible and takes place according to the equation R1R2C. (OOC(CH3)3)2 + H2O reversible H+ R1R2C = O + 2HOOC(CH3)3. The proposed mechanism of hydrolysis includes the fast, quasiequilibrium formation of protonated peroxyketal and subsequent formation of the alkylperoxycarbenium ion. A three-parameter correlation equation is proposed for describing the initial rates of hydrolysis of R1R2C(OO-t-Bu)2 peroxyketals.

  摘要：

  已经制备并表征了环己基和苯基膦酸的叔丁基过氧酯。环己基二过氧膦酸二叔丁基酯可通过过氧化物键的杂溶和均裂而分解。苯基膦酸的单叔丁基和二叔丁基过氧酯仅通过杂化分解。在苯基二过氧膦酸二叔丁基酯的情况下，过氧化物键在两个不同的阶段经历杂化。讨论了叔丁基过氧酯的分解机理与母体酸的p K a值之间的关系。

  The radical polymerization mechanism of styrene initiated by 2,2-bis(t-butyldioxy)alkanes (1) has been studied in benzene. The decomposition products of 1 are acetone, alkyl methyl ketone, t-butyl alcohol, and t-butyl peracetate. Styrene monomer converts to polystyrene along with styrene oxide.

  A volatile cross-linking agent such as liquid peroxide is introduced, at ambient temperature and under atmospheric pressure directly into the input of an extruder at the same pressure as a polyolefin compound to be cross-linked. The resulting compounds are put under pressure within the extruder as the temperature increases so that the mixture reaches its definitive shape at the extruder output and may be fed directly into a hot cross-linking enclosure which is maintained under pressure. The peroxide is thus incorporated in a single operation permitting complete control of the ingredients mixed and allowing perfect homogenization of the mixture while defusion and consequent loss of the highly volatile peroxide are avoided. The system for introducing the highly volatile cross-linking agent includes a peroxide storage tank, a filling pump, a feed vessel, an incremental feed pump with a pressure meter, a flow meter and numerous safety features. These elements control the flow, temperature and ambient conditions of the cross-linking agent feed system within a controlled environment to ensure the safe and precise handling of a highly volatile liquid while at the same time controlling the feeding of the liquid as a function of the material processed by the extruder so that the percentage of the cross-linking agent inserted at the input to the extruder remains at a constant, predetermined percentage, regardless of extruder speed variations. Additionally, various additives which are soluble in the volatile cross-linking agent may be introduced within the feed system therefor in sufficient amounts for effecting protection of the resulting polymer without altering the efficiency of the feed system or that of the additive so that the entire process may be carried out at the processing site without initial preparation of various mixtures to be further processed.

  一种挥发性交联剂，如液态过氧化物，直接在环境温度和大气压力下，以与要交联的聚烯烃化合物相同的压力，直接注入挤出机的进料口。随着温度的升高，混合物在挤出机内受到压力，使其在挤出机的出料口达到其最终形状，并可以直接进入保持在压力下的热交联密闭室中。过氧化物因此在单个操作中被纳入，允许完全控制混合的成分，并允许混合物的完美均质化，同时避免了高度挥发性过氧化物的扩散和损失。引入高度挥发性交联剂的系统包括过氧化物储罐、灌装泵、进料容器、带有压力计的增量进料泵、流量计和众多安全功能。这些元素在受控环境内控制交联剂进料系统的流量、温度和环境条件，以确保在安全和精确处理高度挥发性液体的同时，根据挤出机加工的材料控制液体的进料，使交联剂在挤出机的输入处的百分比保持恒定，而不受挤出机速度变化的影响。此外，可在进料系统中引入可溶于挥发性交联剂的各种添加剂，以足够的量保护所得聚合物，而不会改变进料系统或添加剂的效率，因此整个过程可以在处理现场进行，而无需预先准备各种待进一步加工的混合物。
