Description
技术领域
本发明属于精细化工领域,具体涉及一种1,4-萘二甲酸的制备方法。
背景技术
1,4-萘二甲酸(1,4-NDCA,1,4-naphthalenedicarboxylic acid)是合成荧光增白剂KCB的中间体,故称KCB酸;它也是合成其它染料、颜料、树脂、药物的重要中间体;其本身还可作为混合材料添加剂用于服装材料、髙强度容器材料等材料领域。
目前1,4-萘二甲酸合成工艺主要有以下几种方法:
以1,4-二甲基萘为起始原料,有三种方法:一种是1,4-二甲基萘三步合成法(溴代,氰基取代,水解)(US4375556A、US4376214A、CA1072109A),该方法毒性大、生产成本过髙。二是用强氧化剂(高锰酸钾、重铬酸钾)常压氧化。该方法生产过程中产生的废液废渣难以处理,对环境污染较大,于环保不利,不能应用于工业生产。三是采用液相法催化氧化法(JPS63159344A、JPH06345685A、JP2003286221A、《高效液相法催化氧化制备1,4-萘二甲酸的研究》(刘冰等,第十四届全国染料与染色学术研讨会暨信息发布会论文集),以有机酸作为溶剂,以Co-Mn-Br 三种元素的混合物作催化剂, 或Mn-Br两种元素的混合物作催化剂,空气作为氧化剂进行氧化,该方法溶剂可回收利用,对环境无污染,符合绿色化工发展的总趋势。但是,上述方法的缺点是起始原料1,4-二甲基萘难以获得。
以1-甲基-4-萘甲酸为起始原料,有二种方法:一是用强氧化剂(高锰酸钾、重铬酸钾)常压氧化(US3652667A、GB1173704A)。该方法同样在生产过程中产生的废液废渣难以处理,对环境污染较大,于环保不利,不能应用于工业生产。另一种是以醋酸作为溶剂,以醋酸钴/醋酸锰/酸酸钠混合体系作催化剂,空气作为氧化剂进行氧化(CN201310749296.2《1,4—萘二羧酸的制备方法》)。其缺点也是起始原料1-甲基-4-萘甲酸难以获得。
发明内容
为克服现有技术中1,4-萘二甲酸合成的起始原料难以获得的缺陷,本发明提供一种新的1,4-萘二甲酸制备方法,其特点是,包括以下步骤:
S01、以1-溴化萘为起始原料,与乙酰氯发生Friedel- Crafts反应生成4-溴-1-乙酰萘;
S02、4-溴-1-乙酰萘用次氯酸盐氧化,得4-溴-1-萘甲酸;
S03、4-溴-1-萘甲酸与氰化亚铜在极性非质子溶剂中,在催化剂量的碘化钾和硫酸铜存在下,反应,生成4 - 氰基萘甲酸铜盐配合物;
S04、4 - 氰基萘甲酸铜盐配合物经碱水解,得1,4-萘二甲酸。
本发明中所用起始原料1-溴化萘可用常规方法轻易地由萘的溴化获得。
在步骤S01中,Friedel- Crafts反应的溶剂选择氯乙烯,催化剂采用氯化铝。
在步骤S02中,4-溴-1-乙酰萘的氧化在碱性溶液中进行,氧化剂采用含活性氯14%的次氯酸钠。所得4-溴-1-萘甲酸用40%亚硫酸氢钠溶液和活性炭精制。
在步骤S03中,相对于1摩尔4-溴-1-萘甲酸,氰化亚铜的用量为1-2摩尔,优选1-1.5摩尔。
进一步地,极性非质子溶剂可选用二甲基甲酰胺、喹啉、N-甲基乙酰胺、二甲基乙酰胺、二甲基亚砜、N -甲基吡咯烷酮、六甲基磷酸三酰胺以及喹哪啶,优选二甲基甲酰胺和喹啉。
进一步地,反应在150-250℃的温度下进行,最好在所用溶剂的沸点下进行。
进一步地,加入催化剂有利于反应加速进行。催化剂可采用碘化钾和硫酸铜混合物。
进一步地,反应生成的4 - 氰基萘甲酸铜盐配合物可在冷却反应混合物并加入水或低沸点溶剂后分离出来。所述低沸点极性溶剂可采用低沸点醇,优选甲醇或乙醇。
进一步地,反应生成的4 - 氰基萘甲酸铜盐配合物可不进行分离,直接进行下一步水解。
在步骤S04中,4 - 氰基萘甲酸铜盐配合物无需干燥,可根据公知的方法,例如使用10-35%氢氧化钠溶液在煮沸条件下,在碱性介质中直接皂化。然后将溶液的pH值调到7-8,氧化铜可定量沉淀从而分离。然后,继续添加无机酸,将pH值调至2,形成白色沉淀,过滤,得1,4-萘二甲酸。
根据本发明所述方法得到的萘-1,4-二羧酸不仅原料易得,而且产品不含有色杂质,质量高,可用作染料、紫外线吸收剂、闪烁体和光学增白剂的中间体直接用于进一步合成。

实施例1
在2000mL四口烧瓶中,加入到500mL干燥的氯化乙烯,然后先后加入160 g氯化铝和94g乙酰氯,将该混合物在30-35℃搅拌,直至形成透明溶液。此时,加入207g预先溶解于250mL氯乙烯的1-溴萘,升温至90℃,搅拌30分钟。将反应混合液冷却至室温,所得氯化铝/4-溴-1-乙酰萘络合物沉淀在负压下过滤,用少量氯乙烯洗涤几次。将所得络合物按加入到2000mL2M盐酸中,加热到100℃分解,同时蒸馏去氯乙烯。冷却至室温后,同时搅拌,沉淀,得4-溴-1-乙酰萘结晶。抽滤,用水洗净残酸,干燥,得207g接近无色的产品,其熔点46-48℃。
将所得4-溴-1-乙酰萘结晶加入到2000mL水中,将反应混合物加热到90℃,加入70g 30%氢氧化钠溶液,然后在2 - 3小时流加2000mL含14%活性氯的氯漂白液,同时经冷凝器馏出形成的氯仿。进一步反应一小时,加入100mL 40%亚硫酸氢钠溶液,所得溶液加入5g活性炭脱色,然后用80g浓盐酸酸化pH值至2。将所得4-溴-1-萘甲酸沉淀抽滤,水洗至无氯离子,干燥,得187g近乎无色的酸,其熔点为219-220℃。
125.6g 4-溴-1-萘甲酸、51g铜氰化亚铜加入到330mL二甲基甲酰胺中。然后,在150- 160℃加热回流条件下反应4小时,同时搅拌,其间溶液中有时出现固体物质,随后4-氰基-1-萘酸溴化铜配合物逐渐沉淀。将反应液冷却至100℃,然后用330mL水稀释,在室温下搅拌约1小时,抽滤沉淀,用400mL水洗涤。
将分离得到的4-氰基萘甲酸/溴化铜配合物加入550mL 20%氢氧化钠溶液的中,加热回流5小时。然后将混合物用约220mL浓盐酸调pH值至7.0-7.5,滤除氧化铜沉淀,滤液继续用100mL浓盐酸调pH值至2,1,4-萘二甲酸沉淀析出,抽滤,用水洗涤直至无氯离子,干燥后得到了92g的几乎无色的1,4-萘二甲酸,熔点为315-320℃。
实施例2
4-溴-1-萘甲酸的制备按实施例1的方法进行。
125.6g 4-溴-1-萘甲酸、51g氰化亚铜加入到330mL无水喹啉中。然后在回流条件下加热混合物至235-240℃,反应4小时,形成均匀的深色溶液。将反应液冷却至120℃,然后加入750mL 15%氢氧化钠溶液,产生黄棕色悬浮物,继续加热回流。浓缩物用分液装置弃去比重较大的含水喹啉,在4-氰基萘甲酸/溴化铜配合物完全水解或完全去除喹啉(约6小时)后,将反应混合物冷却至80℃,,将混合物用约230mL浓盐酸调pH值至7.0-7.5,滤除氧化铜沉淀,滤液继续用90mL浓盐酸调pH值至2,1,4-萘二甲酸沉淀析出,抽滤,用水洗涤直至无氯离子,干燥后得到了90g的几乎无色的1,4-萘二甲酸,熔点为315-320℃。
