背景技术
5- 降冰片烯 -2, 3- 二甲酸酐(纳迪克酸酐, Himic anhydride )是一种重要的化工原料,广泛应用于电子信息材料、合成树脂及塑料、农药和制药等众多领域,其制备工艺简单,原料成本较低,此外,其作为原料合成的树脂比用六氢苯酐和四氢苯酐合成的树脂具有更好的气干性、更高的耐热性、更好的光洁度、更高的电性能、耐腐蚀性能和机械强度等。内亚甲基六氢邻苯二甲酸酐为纳迪克酸酐催化剂加氢后的产物。与纳迪克酸酐相比,内亚甲基六氢邻苯二甲酸酐( hexahydro-3,6-methanophthalic anhydride )具有更稳定的化学结构和物理化学性质,具有更低的黏度,其产物具有固体色泽更浅,耐候性更好的特点。因此,其将成为纳迪克酸酐的替代品。随着我国石油工业的不断发展,作为乙烯副产物环戊二烯的产量也在不断增加,但多数未能得到充分的开发利用,为解决我国环戊二烯的综合利用问题,同时为化工行业提供应用前景十分广阔的原材料内亚甲基六氢邻苯二甲酸酐,对其合成方法进行研究具有十分重要的意义。
发明内容
本发明目的在于提供一种以混合碳五为原料经过两步反应生产内亚甲基六氢邻苯二甲酸酐的方法,其生产成本低,污染小;另一目的在于提供一种新的化工原料内亚甲基六氢邻苯二甲酸酐。
为实现本发明的目的,本发明技术方案如下:
以顺丁烯二酸酐和混合碳五(其主要成分为环戊二烯、异戊二烯和间戊二烯)为原料,在 0-5℃ 下,用顺丁烯二酸酐直接吸收环戊二烯生成纳迪克酸酐,经结晶得到纳迪克酸酐纯品。然后,其经催化加氢制备内亚甲基六氢邻苯二甲酸酐。

反应示意图
具体反应步骤如下:
向混合碳五中逐渐加入顺丁烯二酸酐,搅拌,控制反应温度在 0-5℃ ,经气相色谱检测没有环戊二烯时停止反应,离心分离,液体经汽化、压缩、冷凝得到主要成分为异戊二烯和间戊二烯的脱环碳五,固体经结晶得到纳迪克酸酐。然后向生成的纳迪克酸酐中加入 Cu-Ni/ZnO-ZrO2 或 Co-Ni/ZnO-ZrO2 催化剂,其中 Ni 质量百分含量均为 10-30%(Cu 、 Co 和 ZnO 掺杂量不计 ) , ZnO 和 ZrO2 的优选摩尔比为 1∶20-50 ; Cu 、 Ni 优选摩尔比 1∶100-200 ; Co 、 Ni 优选摩尔比为 1∶50-200 。在 100-140 ℃ 、氢气压力 1-4 MPa 的高压釜中进行催化加氢反应 4-6 小时,冷却后过滤催化剂,减压蒸馏即可得内亚甲基六氢邻苯二甲酸酐,收率 90-92% 。
Cu-Ni/ZnO-ZrO2 催化剂制备: 在恒温 25 ℃ 水浴中,搅拌条件下将氨水缓慢滴加到 ZrOCl2·8H2O , Zn(NO3)2 ·6H2O , Ni(NO3)2·6H2O 和 Cu(NO3)2·3H2O 的混合溶液中、溶液完全沉淀后,老化过夜,然后抽滤,去离子水洗涤至 pH 为中性。干燥,得到 Cu-Ni/ZnO-ZrO2 催化剂前驱体,经 400-500 ℃ 焙烧、还原后得到 Cu-Ni/ZnO-ZrO2 催化剂。合成中, Cu(NO3)2·3H2O 和 Ni(NO3)2·6H2O 的优选摩尔比 1∶100-200 ; Zn(NO3)2 ·6H2O 和 ZrOCl2·8H2O 的优选摩尔比为 1∶20-50 ; Ni(NO3)2·6H2O 和 ZrOCl2·8H2O 优选质量比为 1∶1.23-4.75 。
Co-Ni/ZnO-ZrO2 催化剂制备: 在恒温 25 ℃ 水浴中,搅拌条件下将氨水缓慢滴加到 ZrOCl2·8H2O , Zn(NO3)2 ·6H2O , Ni(NO3)2·6H2O 和 Co(NO3)2·6H2O 的混合溶液中、溶液完全沉淀后,老化过夜,然后抽滤,去离子水洗涤至 pH 为中性。干燥,得到 Co-Ni/ZnO-ZrO2 催化剂前驱体,经 450-550 ℃ 焙烧、还原后得到 Co-Ni/ZnO-ZrO2 催化剂。合成中, Co(NO3)2·6H2O 和 Ni(NO3)2·6H2O 优选摩尔比为 1∶50-200 ; Zn(NO3)2 ·6H2O 和 ZrOCl2·8H2O 的优选摩尔比为 1∶20-50 ; Ni(NO3)2·6H2O 和 ZrOCl2·8H2O 的优选质量比为 1∶1.23-4.75 。
本发明有益效果在于:( 1 )该方法直接以混合碳五为原料,不需要对原料混合碳五进行精制分离,大大降低了生产成本,同时经过反应后混合碳五中的环戊二烯被有效脱除,混合碳五可以作为新的化工原料出售;( 2 )该方法使选用复合型催化剂 Cu-Ni/ZnO-ZrO2 或 Co-Ni/ZnO-ZrO2 ,减少了体系内纳迪克酸酐的聚合,避免了酸酐羰基被还原,且该催化剂为非均相催化剂便于分离,减少了催化剂的分离成本;( 3 )原料利用充分,以廉价的乙烯副产物混合碳五为原料制备内亚甲基六氢邻苯二甲酸酐的同时可以得到另一种新的化工原料脱环碳五,加强了对混合碳五的深加工利用,减少了环境污染,便于工业化生产,极具现实意义。
