Low‐Temperature Preparation of a Mesoporous Silica Superbase by Employing the Multifunctionality of a La        <sub >2</sub>2        O        <sub >3</sub>3        Interlayer

摘要

Abstract > A simple and effective approach for the preparation of the solid superbasic La <sub>2</sub> O <sub>3</sub> –SBA‐15‐supported KF (KF/La <sub>2</sub> O <sub>3</sub> –SBA‐15) was developed by a low‐temperature strategy. The KF/La <sub>2</sub> O <sub>3</sub> –SBA‐15 with ordered mesostructure and a high base strength ( H <sub>?</sub> =27.0) was realized at 350?°C in still air, which breaks the traditional method of thermally induced decomposition of basic metal nitrate derived species KNO <sub>3</sub> under higher temperatures (600?°C). The resultant mesoporous basic materials were adopted for the production of 1‐methoxy‐2‐propanol from propylene oxide and methanol. It showed excellent catalytic performance exhibiting 93?% conversion of propylene oxide and 93?% selectivity to 1‐methoxy‐2‐propanol. This performance is better than that over the catalysts without mesoporous silica despite having a higher KF content. </abstract> </span> <span class="z_kbtn z_kbtnclass hoverxs" style="display: none;">展开▼</span> </div> <div class="translation abstracttxt"> <span class="zhankaihshouqi fivelineshidden" id="abstract"> <span>机译：</span><Abstract Type =“Main”XML：Lang =“en”> <标题类型=“main”>抽象</ title> > 制备实体超级洛杉矶的简单有效方法 <sub> 2 </ sub> O. <sub> 3 </ sub> -SBA-15支持的KF（KF / LA <sub> 2 </ sub> O. <sub> 3 </ sub> -SBA-15）由低温策略开发。 kf / la <sub> 2 </ sub> O. <sub> 3 </ sub> -sba-15，具有有序的思科结构和高基础强度（ h </ i> <sub>？</ sub> = 27.0）在静止的空气中在350℃下实现，这破坏了传统的热诱导的碱性硝酸盐衍生物种kno的分解方法 <sub> 3 </ sub> 在较高温度下（＆ 600？°C）。采用所得介孔的缺水碱材料来生产来自环氧丙烷和甲醇的1-甲氧基-2-丙醇。它显示出优异的催化性能，其具有93μl丙烯的转化率和93μl的选择性至1-甲氧基-2-丙醇的选择性。尽管具有较高的Kf含量，但这种性能比没有中孔二氧化硅的催化剂更好。 </ p> </摘要> </span> <span class="z_kbtn z_kbtnclass hoverxs" style="display: none;">展开▼</span> </div> </div> <div class="record"> <h2 class="all_title" id="enpatent33" >著录项</h2> <ul> <li> <span class="lefttit">来源</span> <div style="width: 86%;vertical-align: text-top;display: inline-block;"> <a href='/journal-foreign-16041/'>《ChemCatChem》</a> <b style="margin: 0 2px;">|</b><span>2017年第9期</span><b style="margin: 0 2px;">|</b><span>共7页</span> </div> </li> <li> <div class="author"> <span class="lefttit">作者</span> <p id="fAuthorthree" class="threelineshidden zhankaihshouqi"> </p> <span class="z_kbtnclass z_kbtnclassall hoverxs" id="zkzz" style="display: none;">展开▼</span> </div> </li> <li> <div style="display: flex;"> <span class="lefttit">作者单位</span> <div style="position: relative;margin-left: 3px;max-width: 639px;"> <div class="threelineshidden zhankaihshouqi" id="fOrgthree"> </div> <span class="z_kbtnclass z_kbtnclassall hoverxs" id="zhdw" style="display: none;">展开▼</span> </div> </div> </li> <li > <span class="lefttit">收录信息</span> <span style="width: 86%;vertical-align: text-top;display: inline-block;"></span> </li> <li> <span class="lefttit">原文格式</span> <span>PDF</span> </li> <li> <span class="lefttit">正文语种</span> <span>eng</span> </li> <li> <span class="lefttit">中图分类</span> <span><a href="https://www.zhangqiaokeyan.com/clc/1186.html" title="物理化学（理论化学）、化学物理学">物理化学（理论化学）、化学物理学;</a></span> </li> <li class="antistop"> <span class="lefttit">关键词</span> <p style="width: 86%;vertical-align: text-top;"> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=basicity&option=203" rel="nofollow">basicity;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=fluorides&option=203" rel="nofollow">fluorides;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=lanthanum&option=203" rel="nofollow">lanthanum;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=mesoporous materials&option=203" rel="nofollow">mesoporous materials;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=silicates&option=203" rel="nofollow">silicates;</a> </p> <div class="translation"> 机译：碱性;氟化物;镧;中孔材料;硅酸盐; </div> </li> </ul> </div> </div> <div class="literature cardcommon"> <div class="similarity "> <h3 class="all_title" id="enpatent66">相似文献</h3> <div class="similaritytab clearfix"> <ul> <li class="active" >外文文献</li> <li >中文文献</li> <li >专利</li> </ul> </div> <div class="similarity_details"> <ul > <li> <div> <b>1. </b><a class="enjiyixqcontent" href="/academic-journal-cn_rice-science_thesis/0201259499607.html">Rice planthopper resistance of interspecific protoplast fusin line "pf9279" between O. sative and O.officinalis</a> <b>[J]</b> . <span> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=&option=202" target="_blank" rel="nofollow" class="tuijian_auth tuijian_authcolor"> </a> <a href="/journal-foreign-6912/" target="_blank" rel="nofollow" class="tuijian_authcolor">水稻科学（英文版） .</a> <span>2000</span><span>,第001期</span> </span> </div> </li> <li> <div> <b>2. </b><a class="enjiyixqcontent" href="/academic-journal-cn_journal-shanghai-university-english-edition_thesis/0201269065017.html">Numerical Computing for a Class of Free Multipoint Boundary Value Problem of O.
