Description

一种邻异丙基酚防变色剂及含有防变色剂的邻异丙基酚
技术领域
本发明属于化学领域，特别涉及了一种邻异丙基酚防变色剂及含有防变色剂的邻异丙基酚。
背景技术
邻异丙基酚是重要的有机合成中间体，广泛地用于农药合成及石油化工，合格的邻异丙基酚储存1年以后时常发生颜色变化，含量也有所下降，对下游产品质量影响极大。
发明内容
针对上述问题本发明公开了一种邻异丙基酚防变色剂及含有防变色剂的邻异丙基酚，本发明向邻异丙基酚中加入防变色剂，有效防止了邻异丙基酚的变色和含量下降。
为实现上述目的，本发明的技术方案如下：
一种邻异丙基酚防变色剂，所述防变色剂为85％的磷酸水溶液和乙醇溶液混合得到的磷酸--乙醇溶液体，磷酸--乙醇溶液体中磷酸浓度为25±0.5％。
2.如权利要求1所述的邻异丙基酚防变色剂，其特征在于，所述乙醇溶液浓度为99％。
一种含有防变色剂的邻异丙基酚，包括邻异丙基酚和防变色剂；邻异丙基酚和防变色剂的质量比为1000:0.3；防变色剂为85％的磷酸水溶液和乙醇溶液混合得到的磷酸--乙醇溶液体；磷酸--乙醇溶液体中磷酸浓度为25±0.5％。
进一步的改进，所述乙醇溶液浓度为99％。
进一步的改进，所述含有防变色剂的邻异丙基酚制作方法如下：
步骤一、磷酸--甲酸溶液酸制备:取质量浓度为85％的工业磷酸和质量浓度为99％的乙醇溶液混合均匀，制备得到磷酸-乙醇溶液，磷酸浓度25±0.5％，即得到防变色剂；
步骤二、取邻异丙基酚1000重量份在控温25℃≤T≤80℃、氮保、搅拌的条件下加入0.3重量分防变色剂，均质0.5小时，即得到含有防变色剂的邻异丙基酚。
附图说明
图1为热储前未加入防变色剂的邻异丙基酚图；
图2为热储14天后未加入防变色剂的邻异丙基酚图；
图3为热储28天后未加入防变色剂的邻异丙基酚图；
图4为为热储前加入防变色剂的邻异丙基酚图；
图5为热储14天后加入防变色剂的邻异丙基酚图；
图6为热储28天后加入防变色剂的邻异丙基酚图；
具体实施方式
下面进一步说明其技术方案。
实施例1
磷酸--甲酸溶液酸制备:取工业磷酸(85％)30g,乙醇(99％)70g,制成磷酸乙醇溶液，磷酸浓度为25±0.5％
1、取合格邻异丙基酚1000g+50g，向1000g合格邻异丙基酚产品中在控温、氮保、搅拌的条件下加入0.3g防变色剂，均质0.5小时。
2、储存试验:
----将加入防变色剂的邻异丙基酚取样分析并作好记录，取50g装入磨口瓶中(保持密封无渗漏)，贴好标签。
----将未加防变色剂的邻异丙基酚取50g同样装入磨口瓶中(保持密封无渗漏)，分析邻异丙基酚含量，记录结果，贴好标签。
----将以加入防变色剂及未加防变色剂的邻异丙基置入热储恒温箱中热储，恒温箱温度设置54℃。
---14天、28天后分别取样分析邻异丙基酚含量，并对照观察颜色变化。
3、分析结果记录
Figure BDA0002545765840000021
以上邻异即邻异丙基酚。
4热储前后颜色变化对照图片如图1-6所示：
根据图片可知:
1#未加入防变色剂的热储14天后含量稍有下降，颜色也稍有变深，28天后含量显著下降，颜色加深。
2#加入防变色剂的热储28天含量稳定，颜色无变化。
四、生产应用:
按量加入后无客户投诉。
以上显示和描述了本发明的基本原理、主要特征和本发明的优点。本发明的保护范围并不仅局限于上述实施例，凡属于本发明思路下的技术方案均属于本发明的保护范围。应当指出，对于本技术领域的普通技术人员来说，在不脱离本发明原理前提下的若干改进和润饰，这些改进和润饰也应视为本发明的保护范围。
