Abstract
本发明涉及一种具有足够低的吸湿性的固体,其包含核和包封剂,且所述核中包含谷氨酸-N,N-二乙酸(GLDA)或其衍生物和/或盐;此外还涉及其制备方法。本发明还涉及固体洗涤和清洁剂。
Description
谷氨酸-N,N-二乙酸(GLDA)及其盐和/或衍生物在极宽范围应用技术领域中作为碱土金属离子和重金属离子络合剂受到极大关注。
用于(例如)洗涤剂和清洁剂中的碱土金属离子和重金属离子的络合剂通常在水溶液中合成。在特定的应用场合中,需要其以固态形式存在。
由溶液制备固体的常规方法尤其为结晶和喷雾干燥法。已知(例如)在蒸发或冷却结晶方法中制备的结晶固体可包含结晶水,且在环境条件下,在大多数情况下不如无定形固体吸湿且储存更稳定。另一方面,通过喷雾干燥法(例如在喷雾塔或者在喷雾流化床中)获得无定形固体。该形式的固体通常高度吸湿且在环境条件下敞开储存时,其在短时间内丧失倾倒能力。因此,文献中描述了提高喷雾粉末的储存稳定性的措施,例如US3,932,316中的压实或者用苯甲酸后处理洗涤剂的助洗剂。
本发明的目的是提供一种固体,其包含谷氨酸-N,N-二乙酸(GLDA)和/或其盐或衍生物,且优选具有对加工和应用而言足够低的吸湿性。
本发明涉及一种固体,其优选具有例如对加工和应用而言足够低的吸湿性,其包含下述成分:
a.包含谷氨酸-N,N-二乙酸(GLDA)和/或其盐和/或衍生物(尤其是谷氨酸-N,N-二乙酸(GLDA)和/或其盐)的核,和
b.包含一种通式I化合物(或两种或更多种不同化合物)的涂层:
其中
R为C1-C30烷基或C2-C30链烯基,其额外带有作为取代基的至多5个羟基、甲酰基、C1-C4烷氧基、苯氧基或C1-C4烷氧基羰基且可间隔有至多5个不相邻的氧原子;为下式烷氧基化物基团:
-(CH2)k-O-(A1O)m-(A2O)n-Y
其中A1和A2彼此独立地为具有2-4个碳原子的1,2-亚烷基,Y为氢、C1-C12烷基、苯基或C1-C4烷氧基羰基,k为1、2或3的数,且m和n在每种情况下彼此独立地为0-50的数,其中m+n之和必须至少为4;为烷基中具有1-20个碳原子的苯基烷基;为具有至多3个选自氮、氧和硫的杂原子的5员或6员不饱和或饱和杂环环,其可额外稠合有苯并基团,其中在R的含义中所述的所有苯环和杂环环也可额外带有作为取代基的至多3个C1-C4烷基、羟基、羧基、磺基和/或C1-C4烷氧基羰基;或者为下式基团:
其中A为C1-C12亚烷基桥或者化学键,且
各M彼此独立地为相应化学计量量的氢、碱金属、碱土金属、铵或取代铵(例如有机胺盐),各M尤其彼此独立地为相应化学计量量的氢、碱金属、铵或取代铵(例如有机胺盐)。
本发明还涉及一种制备本发明固体的方法,其中首先引入的种子为包含(或由其组成)谷氨酸-N,N-二乙酸(GLDA)和/或其盐和/或衍生物(尤其是谷氨酸-N,N-二乙酸(GLDA)和/或其盐)的固体,并用至少一种式I化合物进行喷雾造粒或者涂覆(优选在流化床装置中)。
如果核材料(其包含谷氨酸-N,N-二乙酸(GLDA)和/或其盐和/或衍生物)以粉末形式使用,则在喷雾造粒期间,优选首先使该粉末借助涂料物质(其包含通式I的化合物)粘合在一起,从而得到较大颗粒(造粒),然后用所述涂料物质对所述颗粒进行涂覆。如果首先以较大颗粒形式引入核材料,则在喷雾造粒期间,优选直接用所述涂料物质涂覆这些颗粒(涂覆)。
优选谷氨酸-N,N-二乙酸(GLDA)和/或盐为式(II)化合物:
M1OOC-(CH2)2-CH(COOM1)-N(CH2COOM1)2(II)
其中M1为氢、铵或碱金属(例如钠、钾)和/或有机胺(有机胺盐)。特别优选其L形式。此外,优选钠盐。
特别优选如DE19649681所述的式I化合物。
就本发明方法而言,将所述核材料的粉末和/或颗粒作为初始进料(种子)以本身为常规的方式引入本来已知的合适装置(优选流化床喷雾造粒装置,例如Glatt的AGT400型)中并流化。此时,优选造粒粒度为30-300μm(尤其为50-200μm),且涂覆粒度为200-1000μm(尤其为300-1000μm)。
优选所述核材料(包含GLDA的材料)为干燥材料,即所述核材料尤其具有小于10%的含水量(尤其是小于5%)。
优选所述核材料(包含GLDA的材料)以本身为常规的方式通过结晶、喷雾干燥或流化床造粒制备。
所述种子以悬浮状态(流化)保持在流化床中且形成包含至少一种式I化合物的雾化液滴的逐层干燥的表面。在制备过程中,以此方式经由造粒制备的颗粒可通过分级排料装置以灵活方式—例如可自由调节的粒度—从干燥空间移除而不中断干燥操作。在通过单纯涂覆生产的情况下,优选间歇操作。
就喷雾造粒方法而言,参见例如H.Uhlemann,L.“Wirbelschicht-Sprühgranulation[流化床喷雾造粒]”,Springer-Verlag2000(ISBN3-540-66985-X)。
本发明方法是一种如下方法:其中首先引入包含谷氨酸-N,N-二乙酸(GLDA)和/或其盐和/或衍生物的固体作为种子,然后以本身为常规的方式用优选以溶液形式存在(尤其是以水溶液形式存在,其浓度优选为约35-43%,特别优选为约35-42%浓度,尤其优选为约40%浓度)的至少一种式I化合物进行喷雾造粒/涂覆。
优选以如下参数进行喷雾造粒/涂覆:
入口空气温度优选为90-160°C,
产物温度优选为50-120°C,
出口空气温度优选为40-110°C,
进料温度优选为40-100°C。
在本发明方法中,例如将液体原料(例如35-43%浓度,优选35-42%浓度,尤其是40%浓度的式I化合物的水溶液)喷雾至流化于热空气流中的种子(包含谷氨酸-N,N-二乙酸(GLDA)和/或其盐和/或衍生物)上,因此使其干燥,且对所述种子进行涂覆或造粒然后涂覆。
所述流化床装置优选为流化床喷雾造粒机,其例如装备有旋风分离机和/或过滤器和/或湿洗器。
当在标准环境条件,例如25°C和76%相对大气湿度下敞开储存至少1天,优选1周,保持其作为(优选自由流动)粉末或颗粒的稠度时,此时将固体称为非吸湿性的或具有足够低的吸湿性。
本发明固体的核包含谷氨酸-N,N-二乙酸(GLDA)和/或其盐和/或衍生物,优选通式(II)的化合物:
M1OOC-(CH2)2-CH(COOM1)-N(CH2COOM1)2(II)
其中M1为氢、铵、有机胺或碱金属(优选钠)。特别优选所述核包含L-谷氨酸-N,N-二乙酸四钠盐(例如C9H9NO8Na4,CAS号:51981-21-6)。优选所述核材料包含获自AkzoNobel的GL。
所述核可任选包含一种或多种用于碱土金属离子和/或重金属离子的其他络合剂,例如聚合物如聚丙烯酸酯或磺化聚合物(例如磺化多聚物(multipolymer),如获自RoomandHaas(Dow)的Acusol588)或者乙二胺四乙酸(EDTA,如获自AkzoNobel的DissolvineNA),尤其是四钠盐。
所述核特别优选包含GLDA颗粒或共颗粒(即具有能简化GLDA造粒的助剂如聚羧酸酯的颗粒)。
在本发明的上下文中,措辞“GLDA”优选是指谷氨酸-N,N-二乙酸或一种本文所述的盐(例如四钠盐)。
根据本发明制备的固体包含作为涂料的优选基本为式I的化合物,其中可额外存在少量源于式I化合物的制备的原料和/或副产物。取决于所用合成方法,通常式I化合物的纯度为70-99.9重量%,尤其为80-99.5重量%,在每种情况下基于固体含量。
就本发明而言,优选合适的为其中R为C1-C20烷基、C2-C20链烯基或者下式基团的那些式I化合物:
