Description
技术领域
本发明涉及一种制备低甲醇含量的三-(2-羟乙基)-甲基硫酸甲酯铵脂肪酸酯的方法,以及涉及通过该方法获得的织物柔软活性组合物。
背景技术
含有两个疏水长链烃部分的季铵盐已被广泛用作织物柔软剂活性物。平均每分子被两个脂肪酸部分酯化的烷醇胺的季铵盐,通常被称为酯基季铵盐,由于它们的生物可降解性,已广泛替代早期的烷基季铵化合物。
通过用硫酸二甲酯季铵化三乙醇胺的脂肪酸酯而制备的三-(2-羟乙基)-甲基硫酸甲酯铵脂肪酸酯已被广泛用作织物柔软剂活性物。因为硫酸二甲酯是潜在的致癌物质,所以季铵化的进行要使硫酸二甲酯转化完全且得到高的胺转化。已发现通过此方法制备的三-(2-羟乙基)-甲基硫酸甲酯铵脂肪酸酯包含不希望的高含量甲醇。虽然三-(2-羟乙基)-甲基硫酸甲酯铵脂肪酸酯柔软剂活性物质已经使用超过20年,但在这些组合物中的高甲醇含量还没有被注意到。
因为甲醇有毒性且存在工作危害,由此需要使包含三-(2-羟乙基)-甲基硫酸甲酯铵脂肪酸酯的织物柔软剂活性组合物具有低的甲醇含量。同样也需要以简单的方法制备这样的组合物。
已发现包含三-(2-羟乙基)-甲基硫酸甲酯铵脂肪酸酯和具有低甲醇含量的织物柔软剂活性组合物可以在固体酸清除剂存在的情况下,通过用硫酸二甲酯季铵化三乙醇胺来制备。
发明内容
由此本发明涉及制备三-(2-羟乙基)-甲基硫酸甲基铵脂肪酸酯的方法,所述方法包括用甲基硫酸季铵化三-(2-羟乙基)-胺脂肪酸酯的步骤,其中所述季铵化是在固体酸清除剂存在的情况下进行的。
本发明另外涉及一种织物柔软剂活性组合物,其包括65-98重量%的至少一种三-(2-羟乙基)-甲基硫酸甲基铵脂肪酸酯、相应的非季铵化的三-(2-羟乙基)-胺脂肪酸酯、和1-1500ppm的甲醇,所述非季铵化的三-(2-羟乙基)-胺脂肪酸酯的量使该组合物的总胺值为2至低于7mg KOH/g。
本发明的方法包括在固体酸清除剂存在的情况下,用硫酸二甲酯季铵化三-(2-羟乙基)-胺脂肪酸酯的步骤。术语酸清除剂表示与季铵化反应混合物中存在的或季铵化反应中形成的布朗斯台德酸(acid)反应的材料,但是所述材料在季铵化反应中在很大程度上不与硫酸二甲酯反应。优选低于10%,更优选低于5%且最优选低于2%的所用硫酸二甲酯被与所述酸清除剂的反应消耗。
所述固体酸清除剂可以是金属碳酸盐、金属碳酸氢盐、金属氧化物、金属氢氧化物、碱性硅酸盐或碱性铝硅酸盐。所述的固体酸清除剂优选选自碱金属碳酸盐、碱金属碳酸氢盐、碱土金属碳酸盐、碱土金属氧化物和碱土金属氢氧化物。所述的碱金属优选为锂、钠或钾,最优选钠。所述的碱土金属优选为镁或钙或其混合物。适宜的固体酸清除剂为例如碳酸钠、碳酸氢钠、倍半碳酸钠、碳酸钙、碳酸镁、白云石、氢氧化镁碳酸镁复盐(magnesium hydroxyl carbonates)、氧化钙、氧化镁、氢氧化钙或氢氧化镁。最优选的固体酸清除剂是碳酸钠或碳酸氢钠。
所述固体酸清除剂的用量优选高于季铵化反应混合物中存在的以及在季铵化反应中形成的布朗斯台德酸。更优选地,基于季铵化反应混合物的重量,固体酸清除剂的使用量是1-3重量%。
在固体酸清除剂存在的情况下,用硫酸二甲酯进行三-(2-羟乙基)-胺脂肪酸酯的季铵化使得即使在高度季铵化反应中,三-(2-羟乙基)-甲基硫酸甲酯铵脂肪酸酯具有低含量的甲醇。因此,本发明的方法可以提供包括三-(2-羟乙基)-甲基硫酸甲酯铵脂肪酸酯的组合物,其同时具有低甲醇含量和低总胺值。
所述固体酸清除剂优选由平均颗粒尺寸至少为100μm的颗粒,特别是平均颗粒尺寸为100μm-5mm的颗粒组成。平均颗粒尺寸的测量是通过筛分析法测量颗粒尺寸分布的质量中值直径。使用具有优选颗粒尺寸的固体酸清除剂会促进未反应的固体酸清除剂从季铵化反应所产生的粘性反应混合物中分离出来。
优选通过过滤或离心将所述固体酸清除剂从季铵化所产生的反应混合物中分离出。通过过滤或离心分离固体酸清除剂使得包含三-(2-羟乙基)-甲基硫酸甲酯铵脂肪酸酯的组合物仅含有少量的酸性和碱性化合物。
季铵化的步骤可以在溶剂存在的情况下进行,所述溶剂优选选自乙醇、1-丙醇、2-丙醇、乙二醇、二甘醇、丙二醇、二丙醇醚、乙二醇的C1-C4烷基单醚、丙二醇的C1-C4烷基单醚以及它们的混合物。然而,季铵化的步骤优选在没有溶剂的情况下进行。
在本发明所述方法的优选实施方案中,在通过过滤和离心分离固体酸清除剂之前,将选自以下的溶剂加入到由季铵化得到的反应混合物中:乙醇、1-丙醇、2-丙醇、乙二醇、二甘醇、丙二醇、二丙醇醚、乙二醇的C1-C4烷基单醚、丙二醇的C1-C4烷基单醚以及它们的混合物。在过滤或离心之前添加溶剂可以通过降低混合物的粘性而促进未反应的固体酸清除剂从反应混合物中分离。在其他的优选实施方案中,所分离的固体酸清除剂用该溶剂洗涤,由此生产洗涤液,且该洗涤液重新用于在季铵化所得到的反应混合物中添加溶剂。
用溶剂洗涤并重复利用洗涤液,可降低在过滤或离心分离中黏附在未反应的固体酸清除剂上的三-(2-羟乙基)-甲基硫酸甲酯铵脂肪酸酯的损失。
所述季铵化的步骤优选在硫酸二甲酯和三-(2-羟乙基)-胺脂肪酸酯的摩尔比为0.9-0.98,更优选在0.92-0.97时进行。所述季铵化的步骤优选在60-95℃,更优选70-90℃的温度下进行。季铵化可以在任何压力下进行,例如环境压力或降低压力下。季铵化优选进行至基本上所有的硫酸二甲酯已反应。
作为起始材料的三-(2-羟乙基)-胺脂肪酸酯的脂肪酸部分可以衍生于纯的脂肪酸或结构式为RCOOH的脂肪酸的混合物,其中R是烃基。所述的烃基可以是支链的或直链的,优选是直链的。
所述三-(2-羟乙基)-胺脂肪酸酯可以包括结构式为N(CH2CH2OH)2(CH2CH2OC(=O)R)的单酯、结构式为N(CH2CH2OH)(CH2CH2OC(=O)R)2的二酯、以及结构式为N(CH2CH2OC(=O)R)3的三酯,其中R是脂肪酸部分RCOO的烃基。所述的三-(2-羟乙基)-胺脂肪酸酯中脂肪酸部分和氮的平均摩尔比优选为1.4-2.0,更优选为1.5-1.8。在漂洗周期循环织物柔软剂(rinse cycle fabric softener)中,所规定的摩尔比使季铵化产品具有高柔软性能。
与所述三-(2-羟乙基)-胺脂肪酸酯的脂肪酸部分相应的脂肪酸优选的碘值为0.5-120,更优选为1-50,且最优选为30-45。所述碘值是指通过100克脂肪酸的双键反应所消耗的碘的总克数,其由ISO 3961所述方法测得。
三-(2-羟乙基)-胺脂肪酸酯的脂肪酸部分优选具有16-18个碳原子,更优选具有16.5-17.8个碳原子的平均链长。所述的平均链长是基于脂肪酸混合物中单独脂肪酸的重量分数来计算得到的。对于支链脂肪酸,链长是指碳原子最长的连续链。
优选的碘值和平均链长可提供如下合适组合:季铵化反应产物在熔点和粘性方面上具有良好的可加工性,以及在漂洗循环织物柔软剂中具有高的织物软化效率。
为了提供所需的平均链长和碘值,所述脂肪酸部分可以衍生于同时包括饱和及不饱和脂肪酸的脂肪酸混合物。所述的不饱和脂肪酸混合物优选单不饱和脂肪酸。所述三-(2-羟乙基)-胺脂肪酸酯包括低于10重量%,优选低于6重量%的多不饱和脂肪酸部分。适宜的饱和脂肪酸的例子是棕榈酸和硬脂酸。适宜的单不饱和脂肪酸的例子是油酸和反油酸。所述不饱和脂肪酸部分的双键中顺式和反式比例优选高于55:45,且更优选高于65:35。所述多不饱和脂肪酸部分的分数可以通过选择性接触氢化作用降低,所述选择性接触氢化作用是指选择性氢化-CH=CH-CH2-CH=CH-子结构中的一个双键但不氢化单不饱和烃基的双键的氢化反应。
所述的三-(2-羟乙基)-胺脂肪酸酯起始材料优选通过以下方法来制备的:用脂肪酸或脂肪酸混合物酯化三乙醇胺,然后减压移除在酯化期间形成的水。以此类方法制备的三-(2-羟乙基)-胺脂肪酸酯可以不进行进一步提纯使用。所希望的碘值、平均链长、以及脂肪酸部分与氮的摩尔比可以通过选择脂肪酸或脂肪酸混合物,以及选择在酯化反应中所用的三乙醇胺和脂肪酸的摩尔比来轻易调整。所述酯化优选在160-210℃的温度下,在蒸馏出水的环境压力下进行,直到理论水量的60-80%被移除。然后逐步地降低压力,直至最终压力在5-50mbar的范围内,反应继续直至达到1-10mgKOH/g,优选2-8mg KOH/g,和更优选2-5mg KOH/g的酸值。
本发明的方法容许制备本发明所述的具有低含量未季铵化的三-(2-羟乙基)-胺脂肪酸酯和低含量甲醇的织物柔软剂活性组合物。
本发明的织物柔软剂活性组合物包括65-98重量%的至少一种三-(2-羟乙基)-甲基硫酸甲酯铵脂肪酸酯。所述组合物另外包括相应的未季铵化三-(2-羟乙基)-胺脂肪酸酯,其含量总共提供2至低于7mg KOH/g,优选4至低于7mg KOH/g,更优选5至低于7mg KOH/g的组合物总胺值。所述总胺值是通过以下方法测定的:根据美国石油化学家协会的Tf 2a-64方法,利用高氯酸进行非水滴定测定,并以每克样品的mgKOH计算总胺值。
基于组合物的重量,本发明所述的织物柔软剂活性组合物还包括1-1500ppm的甲醇,优选10-1000ppm的甲醇,更优选10-800ppm的甲醇,最优选是100-800ppm的甲醇。该甲醇含量比现有技术中通过三-(2-羟乙基)-胺脂肪酸酯与硫酸二甲酯反应制备的且含有相似量的三-(2-羟乙基)-甲基硫酸甲酯铵脂肪酸酯和三-(2-羟乙基)-胺脂肪酸酯的织物柔软剂组合物的要低。所述组合物的甲醇含量可以通过用提高已知甲醇量以校准的顶空GLC分析法来测定。为了精确的顶空GLC分析法,所述织物柔软剂组合物优选用适当的溶剂(例如二甲基甲酰胺)稀释以降低其粘度。在本发明所述织物柔软剂活性组合物中的低甲醇含量可以降低对安全保护措施的需要,以及对产品标记和分类的需要,并相比较于现有技术的组合物可以提高组合物的闪点。
本发明所述的织物柔软剂活性组合物还可以包括一种或多种其它的有机溶剂。所述的组合物优选包括最高35重量%的溶剂,所述溶剂选自乙醇、1-丙醇、2-丙醇、乙二醇、二甘醇、丙二醇、二丙醇醚、乙二醇的C1-C4烷基单醚、丙二醇的C1-C4烷基单醚以及其混合物。其它溶剂的量最优选是5-20重量%。更优选的溶剂是乙醇、1-丙醇和2-丙醇,最优选乙醇或2-丙醇,且特别是2-丙醇。
本发明所述织物柔软剂活性组合物的三-(2-羟乙基)-甲基硫酸甲酯铵脂肪酸酯优选与上述的本发明方法中优选作为起始材料的三-(2-羟乙基)-胺脂肪酸酯相对应。这意味着优选的三-(2-羟乙基)-甲基硫酸甲酯铵脂肪酸酯可以通过用硫酸二甲酯季铵化三-(2-羟乙基)-胺脂肪酸酯来制备。
