Description

邻苯二醛水溶液的制备方法
技术领域
本发明涉及一种由邻苯二醛缩醛制备邻苯二醛水溶液的方法。
背景技术
邻苯二醛(OPA)水溶液用在杀虫剂领域中。具体的说,这种溶液用在内诊镜的高活性消毒领域中,也用于医疗器械的消毒。
迄今为止,OPA水溶液一直通过将适量OPA溶解在水中来制备。OPA是固体且以结晶形式存在,这种形式的OPA具有一些缺点,由于它有毒且刺激皮肤,因而处理OPA很困难且在配制OPA水溶液中需要相当的安全措施。另外,OPA有结块的趋势,结果是,第一在装料时出现问题,第二需要很长的溶解过程。
例如EP0839789中所描述的,通过将液体OPA缩醛皂化制备来OPA本身,该液态OPA缩醛作为OPA的储存化合物。根据以上文献,采用例如HCl、H2SO4、H3PO4的无机酸或例如乙酸、甲酸、对甲苯磺酸或甲磺酸的有机酸,在0到7之间的pH下通过水解进行皂化。
例如,EP0843966公开了OPA或OPA缩醛用于制备同样用在杀虫剂领域中的OPA-戊二醛水溶液的用途,根据该专利,通过在戊二醛水溶液中裂解OPA缩醛并除去消去的醇得到OPA-戊二醛水溶液。
发明内容
本发明的目的在于制备OPA水溶液,同时避免使用结晶OPA的缺点。
因此本发明涉及邻苯二醛水溶液的制备方法,该方法包括将邻苯二醛的缩醛加到水中,随后通过加酸,将pH调为小于7,接着,在10℃到90℃的温度下,通过消去相应的醇,该缩醛转化为邻苯二醛。
在本发明的方法中,将OPA缩醛加到或乳化到水中,并通过水解将其溶解。考虑烷基部分具有1到6个碳原子的二烷基缩醛(开链缩醛)或二烷氧基酞烷(dialkoxyphthalanes)(环状OPA缩醛)作为该OPA缩醛。优选的是,烷基部分具有1到4个碳原子的二烷氧基酞烷或二烷基缩醛,特别优选的是,烷基部分具有1到2个碳原子。
根据本发明,将足量的缩醛加到水中并将其溶解,酸化后,得到重量浓度为0.025%到9%的OPA水溶液。优选的是,溶液的重量浓度为0.05%到5%,特别优选的是,溶液的重量浓度为0.5%到2%。此处必须要注意到,根据1H-NMR,水溶液的平衡为25%的OPA和75%的半缩醛。
为了得到更高浓度的溶液,可以在溶液中加入增溶剂,例如聚乙二醇,或者加入选自例如N-甲基吡咯烷酮、丙酮等的酮和例如戊二醛等的醛的可与水混溶的溶剂,结果可以得到浓度达到50重量%的OPA。
为了将缩醛转化为OPA,将酸加到水溶液中使得pH调为小于7。考虑例如硫酸、HCl等无机酸,或例如甲酸、乙酸、二羟乙酸的有机酸作为酸。优选的是,使用硫酸、二羟乙酸或甲酸。
pH应小于7,优选的是等于5,特别优选的是至多为3。
在10℃到90℃的温度进行裂解,优选的是在20℃到50℃。优选的是,搅拌该溶液。
如果将缩醛置于水中,那么首先出现2相乳液,该乳液仅仅在pH调到小于7以后转化成均相溶液。
与使用OPA本身相比,本发明的方法中的有利之处是可以制备更高浓度的溶液(9%比5%),因为通过酸化消去乙醇有利于所形成的OPA的溶解。
如果适当的话,裂解以后,例如通过添加诸如NaHCO3、NaOH、KOH等的无机碱,可以中和得到的OPA水溶液,或者将pH调到4或10,优选的是调到8。另外,如果希望的话,可以通过蒸馏从溶液除去消去的醇,然而,结果是溶解度又降到5%。
而且,除了以上提及的增溶剂以外,可以将其它常用的助剂,例如稳定剂、抗氧化剂、香料、染料等加到根据本发明制备的溶液中。
根据本发明制备的OPA水溶液特别适于用在杀虫剂领域中,具体的是,其特点在于以下事实,首先,由于直接使用缩醛,所以省略了OPA的最后制备步骤,这节约了成本,第二,通过使用OPA缩醛提供了明显的可处理性优点。
然而,本发明OPA水溶液的制备方法还可以在自动消毒设备中进行。
本发明还涉及OPA缩醛作为原料用于制备用在杀虫剂领域中的OPA水溶液的用途。
