Abstract
一种包含Mg、Ti、卤素,以及式(I)或式(II)的电子供体的用于烯烃聚合的固体催化剂组分,当用烷基铝和任选的外部电子供体活化时,能够在烯烃聚合中产生高活性和立体专一性。
Description
技术领域
本公开内容涉及用于烯烃(特别是丙烯)聚合的催化剂组分,所述催化剂组分包含负载有Ti原子的二卤化镁基载体和含有酯和碳酸酯官能团的电子供体化合物。本公开内容还涉及由所述组分获得的催化剂,及其在烯烃、特别是丙烯聚合方法中的用途。
背景技术
本领域中已经公开了用于烯烃的立体专一性聚合的催化剂组分。就丙烯的聚合而言,使用齐格勒-纳塔催化剂,其通常包含与Al-烷基化合物结合使用的固体催化剂组分,所述固体催化剂组分由负载有钛化合物和内部电子供体化合物的二卤化镁构成。然而,当需要更高的聚合物结晶度时,还需要外部供体(例如烷氧基硅烷)以获得更高的全同立构规整度。邻苯二甲酸的酯,特别是邻苯二甲酸二异丁酯在催化剂制备中用作内部供体。邻苯二甲酸酯作为内部供体与作为外部供体的烷基烷氧基硅烷结合使用。该催化剂体系在活性、全同立构规整度和二甲苯不溶性方面具有良好的表现。
与使用这种催化剂体系相关的问题之一是,邻苯二甲酸酯最近由于与其使用相关的医学问题而引起关注,并且该类别中的一些化合物已被归类为重度健康问题的来源。
因此,研究活动一直致力于发现在用于丙烯聚合的催化剂组分的制备中使用的可替代类型的内部供体。
感兴趣的类型之一是在US7,388,061中公开的属于式R1-CO-O-CR3R4-A-CR5R6-O-CO-R2的酯,其中R1和R2基团可以相同或不同,可以是具有1-20个碳原子的取代或未取代的烃基,R3-R6基团可以相同或不同,可以选自于由氢、卤素或具有1-20个碳原子的取代或未取代的烃基所组成的组,R1-R6基团任选地含有取代碳原子、氢原子或二者的一个或多个杂原子,所述杂原子选自于由氮、氧、硫、硅、磷和卤素原子所组成的组,R3-R6基团中的两个以上可以连接形成饱和或不饱和的单环或多环;A是单键或在两个自由基之间的链长为1-10个原子的二价连接基团,其中所述二价连接基团选自于由脂族、脂环族和芳族二价基团所组成的组,并且可以带有C1-C20直链或支链取代基;上述二价连接基团和取代基中的一个或多个碳原子和/或氢原子可以由选自于由氮、氧、硫、硅、磷和卤素原子所组成的组的杂原子取代,并且在所述连接基团以及上述R3-R6基团上的两个以上取代基可以连接形成饱和或不饱和的单环或多环。
PCT申请WO2010078494公开了作为内部供体的1,2-亚苯基芳族二酯,可有效用于制备用于丙烯聚合的催化剂。
一般来说,如PCT申请WO2011/068775和PCT申请WO2011/068770中所述,用氯甲酸酯衍生物代替芳族酸衍生物在性质、尤其是在立体专一性方面明显恶化。
US2008/0194782描述了对应于α-羟基酯的碳酸酯的某些结构。然而,该结构未在制备用于烯烃聚合的催化剂中使用。
发明内容
令人惊奇的是,申请人已经发现,同时含有碳酸酯和酯官能团的非二醇衍生物类供体产生了显示出良好的活性和立体专一性平衡的催化剂。
因此,本公开内容提供了用于烯烃聚合的催化剂组分,所述催化剂组分包含Mg、Ti、卤素,以及式(I)或式(II)的电子供体,
其中:
-R1和R3选自于任选地含有选自于卤素、P、S、N和O的杂原子的C1-C15烃基;
-R5-R7基团独立地为氢或C1-C20烃自由基,任选由选自于卤素、P、S、N、O和Si的杂原子取代,其可以稠合在一起形成一个或多个环;
-R8-R11独立地选自于氢、卤素或任选由选自于卤素、P、S、N、O和Si的杂原子取代的C1-C15烃基;
-R12-R13基团彼此相同或不同,为氢或可以稠合在一起形成一个或多个环的R1基团,并且n为0-2的整数。
具体实施方式
式(I)的优选结构是其中R5-R7基团中至少一个是C1-C20烃自由基、优选C1-C10烷基基团的结构。在具体实施方案中,R5和R7是C1-C10烷基基团。
式(II)的优选结构是其中R8-R11基团中的至少一个、并优选至少两个不同于氢的结构。特别地,优选的结构是其中芳环在3位和/或5位被取代的结构。在所有这些情况下,R8-R11基团优选选自于C1-C5烷基基团。特别优选的是在3位和/或5位被烷基取代。在特别优选的实施方案中,5位的烷基是仲烷基基团或叔烷基基团,特别是叔丁基。
优选的结构是其中n为1的结构,优选与R12和R13中的至少一个氢化相结合,特别是与如上所述取代的芳环相结合。
在式(I)-式(II)的结构中,R1和R3基团独立地选自于C1-C15烷基基团、C6-C14芳基基团、C3-C15环烷基基团,以及C7-C15芳烷基或烷芳基基团。更优选地,R1和R3基团独立地选自于C1-C10烷基基团,甚至更优选选自于C1-C5烷基基团,特别是乙基。
优选地,在固体催化剂组分中的电子供体化合物的最终量为1-25wt%,优选3-20wt%。
式(I)-式(III)的结构的非限制性实例如下:

落入式(I)中的化合物可以通过在碱(例如叔胺)的存在下,使水合物HO-A-COOR3与氯甲酸烷基酯R1O-CO-Cl反应来制备。在本公开内容的固体催化剂组分中,相对于所述催化剂组分的总重量,固体催化剂组分中Ti原子的量优选高于2.5wt%,更优选高于3.0wt%。
如上所述,除了上述电子供体外,本发明的催化剂组分还包含Ti、Mg和卤素。特别地,催化剂组分包含具有至少一个Ti-卤键的钛化合物和负载在镁卤化物上的上述电子供体化合物。镁卤化物优选处于活性形式的MgCl2,其作为用于齐格勒-纳塔催化剂的载体而公开。专利USP 4,298,718和USP 4,495,338是首先描述在齐格勒-纳塔催化中使用这些化合物的专利。在这些专利中公开的是,用于烯烃聚合的催化剂组分中用作载体或共载体的活性形式的二卤化镁的特征在于X射线谱,其中出现在非活性卤化物的光谱中的最强衍射线强度降低,并被最大强度相对于更强烈的线的较低角度移位的光晕代替。

固体催化剂组分的制备可以根据多种方法进行。一种方法包括在约80℃-120℃的温度下,在电子供体化合物存在下,镁醇化物或氯代醇化物(特别是根据USP 4,220,554制备的氯代醇化物)和过量的TiCl4之间的反应。
根据优选的方法,固体催化剂组分可以通过使式Ti(OR)m-yXy的钛化合物(其中m是钛的化合价,y是1和m之间的数,优选TiCl4)与衍生自式MgCl2.pROH的加合物(其中p为0.1和6之间的数,优选2-3.5,R为具有1-18个碳原子的烃自由基)的氯化镁反应。加合物可以通过在加合物的熔融温度(100℃-130℃)下搅拌,在与加合物不混溶的惰性烃的存在下将醇和氯化镁混合,来适当地制备为球形。然后,乳液被迅速淬灭,从而使处于球形粒子形式的加合物固化。根据该方法制备的球形加合物的实例在USP 4,399,054和USP 4,469,648中进行了描述。如此获得的加合物可以与Ti化合物直接反应,或者可以预先进行热受控脱醇(80℃-130℃),以获得其中醇的摩尔数低于3、优选0.1和2.5之间的加合物。与Ti化合物的反应可以通过将加合物(脱醇或原样)悬浮在冷的TiCl4中来进行;将混合物加热至80℃-130℃,并在该温度下保持0.5-2小时。用TiCl4的处理可以进行一次或多次。电子供体化合物优选在用TiCl4处理期间加入。例如,在欧洲专利申请EP-A-395083、EP-A-553805、EP-A-553806、EPA601525和WO98/44001中描述了处于球形形式的催化剂组分的制备。
根据上述方法获得的固体催化剂组分的表面积(通过BET法)在20m2/g和500m2/g之间,优选50m2/g和400m2/g之间,总孔隙率(通过BET法)高于0.2cm3/g,优选在0.2cm3/g和0.6cm3/g之间。由于孔径高达 孔隙率(Hg法)可以为0.3-1.5cm3/g,优选0.45-1cm3/g。
固体催化剂组分的平均粒径为5-120μm,更优选10-100μm。
在任何这些制备方法中,所需的电子供体化合物可以原样加入,或者以可替代的方式,它可以通过使用能够通过以例如如转化的化学反应的方式转化为所需的电子供体化合物的合适前体原位获得。
不考虑所使用的制备方法,式(I)的电子供体化合物的最终量为使得其相对于Ti原子的摩尔比为0.01-2,优选0.05-1.5。

第一步:在500mL圆底烧瓶中,在室温氮气下,加入2,6-二甲苯酚(54.5g,0.45mol)、庚烷(130mL)、叔丁醇(66g,0.9mol),然后在搅拌下滴加浓H2SO4(28.4mL,0.54mol)。1小时后反应完成,用水和乙醚稀释混合物。将有机层分离并用水洗涤直至中性pH,然后用Na2SO4脱水,蒸除溶剂,得到81.3g 4-叔丁基-2,6-二甲苯酚,GC纯度为98wt%(产率98%),其不经进一步纯化即用于下一步骤。
第二步:在2升圆底烧瓶中,在氮气下加入4-叔丁基-2,6-二甲苯酚(132.4g,0.74mol)、THF(750mL)和乙醇钠(62.9g,0.9mol)。反应后30分钟后,缓慢滴加二乙基氨基甲酰氯(122mL,0.97mol)。通过GC对反应进行监测,加入额外的乙醇钠和二乙基氨基甲酰氯以将起始物完全转化。然后用水和异己烷稀释混合物,分离有机层并用水洗涤至中性pH,然后用Na2SO4脱水,蒸除溶剂,得到197.8g 4-(叔丁基)-2,6-二甲基苯基二乙基氨基甲酸酯,GC纯度为98wt%(产率94%),其静置时固化。该产物不经进一步纯化即用于下一步骤。
第三步:在2升圆底烧瓶中,在氮气下加入THF(770mL)、4-(叔丁基)-2,6-二甲基苯基二乙基氨基甲酸酯(173.5g,0.63mol)和二异丙胺(8.8mL,0.063mol),然后将混合物冷却至0℃并滴加n-BuLi(2.5mol/L己烷溶液,520mL,1.3mol)。然后移除冷却浴,使反应温热至室温。在此温度下30分钟后,用水和乙酸乙酯稀释反应物。将有机层分离并用水洗涤至中性pH,然后用Na2SO4脱水,蒸除溶剂,得到177.4g 2-(5-(叔丁基)-2-羟基-3-甲基苯基)-N,N-二乙基乙酰胺,GC纯度为94%(产率96%),其不经进一步纯化即用于下一步骤。
第四步:在圆底烧瓶中加入2-(5-(叔丁基)-2-羟基-3-甲基苯基)-N,N-二乙基乙酰胺(来自前一步骤,纯度94%,170g,0.57mol)、乙醇(200mL)和浓H2SO4(30.4mL,0.57mol)。使混合物回流并保持该温度5小时,然后用水和乙酸乙酯稀释。将有机层分离并用水洗涤至中性pH,然后用Na2SO4干燥,蒸除溶剂,得到深色油状物,将其通过庚烷结晶纯化,得到86.1g5-(叔丁基)-7-甲基苯并呋喃-2(3H)-酮,GC纯度为98wt%(收率72%)。
第五步:用乙醇(200mL)和催化量的浓H2SO4对来自前一步骤的5-(叔丁基)-7-甲基苯并呋喃-2(3H)-酮(83.4g,0.4mol)进行处理,回流30分钟,然后对混合物进行处理,得到2-(5-(叔丁基)-2-羟基-3-甲基苯基)乙酸乙酯。
第六步:除了使用2-(5-(叔丁基)-2-羟基-3-甲基苯基)乙酸乙酯代替2-羟基-3,5-二异丙基苯甲酸乙酯以外,其方法与合成实施例1中所用的相同。
