本文对双季戊四醇及其衍生物的合成与废水处理工艺进行了系统的研究。
首先，以甲醛、乙醛和氢氧化钠为原料，对单、双季戊四醇的合成工艺进行了研究。
为提高双季戊四醇的选择性，系统地考察了反应物的物质的量之比、反应终温、单季戊四醇加入量等因素对反应的影响，确定了最佳反应条件：在反应终温为46℃，n(甲醛):n(乙醛):n(氢氧化钠) = 6.0:1:1.2 时，加入质量分数为 6 wt%的单季戊四醇，乙醛的转化率接近100.0%，单季戊四醇的选择性为91.2%，双季戊四醇的选择性为 4.7%。
接着，以双季、丙烯酸为原料，合成了双季戊四醇六丙烯酸酯。
考察了阻聚剂和酸催化剂的加入量对反应的影响，确定了最佳实验条件：在酸醇摩尔比为7.5:1，对苯二酚加入量3 wt%，对甲苯磺酸加入量为4 wt%时，双季戊四醇六丙烯酸酯收率为90.6%。
此外，还建立了一种基于TiO2 光催化剂的单（双）季戊四醇废水处理工艺。
制备了一系列的TiO2 催化剂用于单（双）季戊四醇的废水处理，并发现TiO2-HY 催化剂具有较高的催化活性和稳定性。
通过XRD，SEM，XPS 等系列表征，发现TiO2-HY 催化剂粒径22.6 nm，以金红石相存在。
pH 为6，50 mL 废水中催化剂加入量为0.06 g 时，在光照16 h，废水中总有机物的降解率可达90.5%。

Synthesis of DPE and its derivative, together with the technology for the disposal of its wastewater, are studied in this paper. The synthesis of pentaerythritol (PE) and DPE were studied systematically, using formaldehyde, aldehyde and骚年美女网NaOH as the starting material. The influence of the molar ratio of the reactants, final reaction temperature, and dosage of PE were optimized. The conversion of aldehyde is nearly 100.0% and the selectivity of PE and DPE are 91.2% and 4.7%, respectively, while the final reaction temperature is 46℃, the molar ratio is n(formaldehyde): n(aldehyde): n(NaOH) = 6.0:1:1.2, and the dosage of PE is 6 wt%. The synthesis of dipentaerythritol hexaacrylate was also studied, using DPE, crylic acid as the starting material. The influence of dosage of inhibitor and acid catalyst were optimized. The yield of dipentaerythritol hexaacrylate is 90.6%, while the molar ratio is n(crylic acid): n(DPE) = 7.5:1, tydroquinone and 4-methylbenzenesulfonic acid is 3 wt% and 4 wt%, respectively. In addition, a process for the photodegradation of PE (DPE) wastewater catalyzed by nano TiO2 is established.A series of TiO2 catalysts were prepared and tested. TiO2-HY was found to have good activity and stability. The TiO2-HY catalyst is proved to be rutile phase with a particle size of 22.6 nm based on XRD, SEM and XPS characterizations. The degradation efficiency is 90.5% in solar light under the optimal operating conditions catalyzed by the TiO2-HY, while the pH value is 6, the amount of catalyst is 0.06 g and the time is 16 hours.Keywordsdipentaerythritolsynthesisderivative wastewater treatment TiO2II前言前言双季戊四醇（双季）和单季戊四醇（单季）都是重要的精细化工中间体[1-5]，广泛应用于航空航天、高分子、印刷纺织、涂料等行业。
