Description
本发明涉及溶剂领域。更具体地说，本发明涉及在低温下溶解油的方法。本发明另一主题是一种以1，1，1，3，3-五氟丁烷(HFC-365mfc)和1，1，1，2，3，4，4，5，5，5-十氟戊烷(HFC-43-10mee)为基础的新颖的组合物。
文献WO00/56833公开了基本上由1，1，1，3，3-五氟丁烷(HFC-365mfc)和1，1，1，2，3，4，4，5，5，5-十氟戊烷(HFC-43-10mee)或九氟甲氧基丁烷组成的准共沸二元组合物。该文献还公开了基本上由1，1，1，3，3-五氟丁烷(HFC-365mfc)、1，1，1，2，3，4，4，5，5，5-十氟戊烷(HFC-43-10mee)或九氟甲氧基丁烷和反式-1，2-二氯乙烯(t-DCE)、正丙基溴、丙酮、甲醇、乙醇或异丙醇组成的准共沸三元和四元组合物。
文献WO00/56833的实施例4和5公开了某些组合物在环境温度下的油溶解性试验。由此，用矿物油对含31wt％43-10mee、31wt％365mfc和38wt％t-DCE的组合物作了评价(表4)以及用DC-200硅油对含33wt％43-10mee、28wt％365mfc和39wt％t-DCE的组合物作了评价(表5)。
然而，该文献的三元组合物在要求低温下操作的应用中(例如在医药领域或其它一些领域中)是无效的。
为此，本申请人公司开发了一种在低温下溶解油的方法。
本发明的第一主题是在低温下溶解油的方法，其特征是使用含有1，1，1，3，3-五氟丁烷(HFC-365mfc)、1，1，1，2，3，4，4，5，5，5-十氟戊烷(HFC-43-10mee)、反式-1，2-二氯乙烯(t-DCE)和1-10wt％含2-4个碳原子的醇的组合物。
根据本发明的方法优选是在低于10℃的温度下进行。0-8℃之间的温度也是优选的。选用3-6℃的温度是有利的。
优选使用的组合物是含有40-69wt％的包含1，1，1，3，3-五氟丁烷和1，1，1，2，3，4，4，5，5，5-十氟丁烷的二元混合物、30-50wt％的反式-1，2-二氯乙烯和1-10wt％的含2-4个碳原子的醇。
使用的组合物有利的是含有45-64wt％的HFC-365mfc和HFC-43-10mee的二元混合物、35-45wt％的反式-1，2-二氯乙烯和1-10wt％的含2-4个碳原子的醇。
该组合物中醇的含量有利的是1-5wt％。
乙醇、丙醇、异丙醇、丁醇、仲丁醇(仲丁醇)或叔丁醇都适合使用。优选使用的是异丙醇或仲丁醇。有利地优选使用仲丁醇。
1，1，1，2，3，4，4，5，5，5-十氟戊烷的优选含量至少是该二元混合物的17wt％。
本发明的方法适合于矿物油或硅油。可以将该方法应用于油在基体(例如厨房用具)上的均匀沉积。特别是很适用于医用等级的硅油的沉积，尤其是沉积在医用仪器上，如注射器针头或导管。这是因为硅油是用作皮下医用注射器的润滑剂，来减轻针扎入患者皮内所引起的疼痛。
本发明的方法适用于很不同的固体表面(金属组件、玻璃、塑料、复合材料)的清洗、脱脂和干燥。它们也可在印刷电路制造中用于除去用以改进焊接质量的物质的残留。这种清除操作在该领域中称为“去焊”。
本发明的第二主题是一种含有1，1，1，3，3-五氟丁烷(HFC-365mfc)、1，1，1，2，3，4，4，5，5，5-十氟戊烷(HFC-43-10mee)、反式-1，2-二氯乙烯(t-DCE)和1-10wt％含4个碳原子的醇的组合物。
根据本发明第二主题特别优选的组合物含有40-69wt％的包含1，1，1，3，3-五氟丁烷和1，1，1，2，3，4，4，5，5，5-十氟戊烷的二元混合物、30-50wt％的反式-1，2-二氯乙烯和1-10wt％的含4个碳原子的醇。
优选含有45-64wt％的HFC-365mfc和HFC-43-10mee的二元混合物、35-45wt％的反式-1，2-二氯乙烯和1-10wt％的含4个碳原子的醇的组合物是有利的。
该组合物中醇的含量有利的是在1-5wt％之间。
选择仲丁醇作为醇是有利的。
1，1，1，2，3，4，4，5，5，5-十氟戊烷的优选含量为该二元混合物的至少17wt％。
根据本发明第二主题的组合物可用于工业中很不同的固体表面(金属组件、玻璃、塑料、复合材料)的清洗、脱脂和干燥。其也可在印刷电路制造中用于除去用以改进焊接质量的物质的残留。这种清除操作在该领域中称为“去焊”。
此外，该组合物还能用来作为聚氨酯泡沫的发泡剂、作为气溶胶喷射剂、作为热交换流体、作为织物干洗剂或作为制冷装置的清洁剂。
实验部分
实施例1
硅油溶解试验的说明
使用的是Crompton公司(Greenwich，USA)的Crompton L9000-1000硅油。这是一种透明的液体羟基聚二甲基硅氧烷，密度在环境温度下(22℃)为0.97，沸点大于200℃以及闪点为132℃(宾斯克-马丁闭杯方法)。
混合物是在环境温度下也就是在22℃下制备的。
由此，将18ml基于365mfc和43-10mee(待测试的)的组合物和1.94g硅油加到50ml的烧瓶中，也就是制备了10vol％的溶液。随后将该混合物用手工搅拌5分钟。
由此制得的一部分混合物在环境温度下(22℃)放置24小时。另一部分在低温(6℃)下放置7天。
在不同温度下经贮存期之后，仔细观察该混合物的外观。如果该混合物是透明、纯净、均匀、单相和稳定的，则它被认为是在环境温度或6℃下可溶的。
制备了以下的组合物：
组合物A：80wt％HFC-365mfc和20wt％HFC-43-10mee
组合物B：48wt％HFC-365mfc和12wt％HFC-43-10mee和40wt％反式-1，2-二氯乙烯
组合物C：44wt％的HFC-365mfc和11wt％HFC-43-10mee、40wt％的反式-1，2-二氯乙烯和5wt％的仲丁醇
结果
| 组合物 | 22℃下的可溶性 | 6℃下的可溶性 |
| 组合物A | 不溶 | 不溶 |
| 组合物B | 可溶 | 不溶 |
| 组合物C | 可溶 | 可溶 |
实施例2
可燃性试验的说明
为评价这些组合物的可燃性，根据ASTM D3828标准方法，Setaflash闭杯闪点法，测定了它们的闪点。该闪点是在液体释放蒸气的量足以在其表面上形成在空气中在点火源作用下是可燃的但当该活化能撤离时就不能持续燃烧的混合物时的最低温度。
为了得到可靠的结果，对于每种组合物重复5次测量。
结果
| 组合物 | 闪点 |
| 组合物A | 无 |
| 组合物B | 无 |
| 组合物C | 无 |
实施例3
测定蒸发速度的说明
使用一种方形的不锈钢筛，每边长为4厘米且每厘米有30根丝。这种类型的筛具有密集的筛目，使它在浸渍后能得到良好的溶剂保留。
将筛浸入装有80ml在环境温度下保持的试验组合物的100ml烧杯中，烧杯内有受控的和稳定的排气。
当完全浸入的筛从试验组合物中取出时的这一瞬间启动测量蒸发速度的秒表。通过观察该组合物随时间移动的前部(在蒸发结束时，该前部消失了)来确定蒸发的终点。大约进行了十五次测量并在下表中列出这些测量的平均值。
结果
| 组合物 | 蒸发时间 |
| 组合物C | 14秒 |
