1908被浏览313903分享邀请回答/p/22339684，下面的内容可能有误，请参考最后说一下硅的来历。当时造元素名称的汉字的选择是：古已有之就不变，如金银铜铁；之前按照性质命名的改成形声字：轻气～氢气，淡气～氮气，养气～氧气，绿气～氯气，淡气意思是把氧气冲淡了，其他不解释了；其他的尽量按音译配形声：helium～氦，boron～硼，aluminium～铝。钾是因为很活泼，取甲之意，同时拉丁文音译Kalium(感谢回复)。最后说一下硅，这个字的造字和使用过程堪称曲折。考虑音译，silicon，应该译为xi音；考虑分布在土壤和岩石中，于是从石和土，于是翻遍各种字典找到这么一个字：菜畦的畦，过去读xi(一声)，现在读qi(二声)，于是这个集形声会意音译为一体的字就成了：硅(读xi)，在教材中印出来以后，可能当时注音还不怎么普及，全国的中学老师都管这个字读gui，大家都按桂、闺的音念了。也怪造字的人脑洞太大，大家压根没想到这个字可以念xi。等到造字人发现已经全国(民国)上下齐声念硅已经过了很久了，于是抖了个机灵，换成矽字你们总不会念错了吧？尽管含义没有硅那么丰富了，至少保证了音译。于是就全国上下改教材然后就带到台湾去了。台湾现在还管Si叫做矽。谁能告诉我手机传图怎么能传上来清晰的？建国以后，革各种命，包括这个矽字。大家说化学里念xi的字太多了，元素周期表里除了Si还有两个，锡和硒，锡和矽还在同一族念起来就成了碳矽锗锡铅，容易混淆，对了还有烯。之前那个硅字就不错嘛，什么容易读错？没关系，那就读gui吧，顺应人民意愿嘛～于是就成了现在这个样子…最早的一批元素名称是这位先生造的：徐寿头一次破百好激动，说明一下，关于硅的那一段，是之前在一篇文章里读到的，刚刚找到了那篇文章，没有署名作者，不过作者应该也是一位老先生原文比我写的好多了，值得一看。71563 条评论分享收藏感谢收起2.4K172 条评论分享收藏感谢收起印字加偏旁变新字,再组词_百度知道

这里讨论的是在1000℃左右煤炼焦所得的高温煤焦油，又称煤焦油。在常温下煤焦油是一种比重为1.17～1.19的黑褐色粘稠液体。
1．煤焦油的化学组成煤焦油组成中包括了如苯、苯酚这样低分子量的简单物质，直到甚至在真空下也不易蒸发的，分子量达数千的非常复杂物质，因此是一种十分复杂的混合物。煤焦油中有机化合物估计有一万种以上，已被鉴定的约有500多种。煤焦油化学组成特点是：①主要是芳香族化合物，而且大多数是两个环以上的稠环芳香族化合物，而烷烃、烯烃和环烷烃化合物很少；②还有杂环的含氧、含氮和含硫化合物；③含氧化合物如呈弱酸性的酚类以及中性的古马隆、氧芴等；④含氮化合物主要包括弱碱性的吡啶、喹啉及它们的衍生物，还有吡咯类如吲哚，咔唑等；⑤含硫化合物是噻吩、硫酚、硫杂茚等；⑥煤焦油中各种烃的烷基化合物数量甚少，而且它们的含量随着分子中环数增加而减少。 虽然煤焦油中组分是多种多样的，但大多数组分在煤焦油中的含量不高或极微。在煤焦油中含量占1％以上的组分只有13种。1. 2 国内外煤焦油工业的加工分离现状国外煤焦油加工工业较发达的国家有德国、日本、美国、英国、法国、意大利、前苏联等 ,虽然工艺有一定的差别 ,但都基于相同的原理.基本过程为:粗焦油→脱水→过滤脱渣→加碱液防设备腐蚀→负压下 150 - 180℃脱水脱轻油→无水焦油加热气化→二次闪蒸分离沥青→各种油蒸汽冷凝分成不同馏份[ 5 ].其中 ,德国和日本已将煤焦油的分离和利用的重点由高含量组分转向低含量组分 ,以从中获取合成精细化学品所需的高附加值成分 ,并且成功地开发出一系列先进的煤焦油加工新工艺.德国是最早利用煤焦油的国家.世界闻名的一些工艺流程几乎都是德国斯蒂尔公司和考伯斯公司设计的 ,投入相当大的力量 ,积极开发与完善加工新技术 ,扩大产品品种 ,提高产品的质量等级.目前 ,吕特格公司 (RutgersWerkeAG)的焦油加工能力为 150万 t / a,已能生产 500多种芳烃产品 ,煤焦油的化工利用率接近 60% ,位居世界之首.日本的焦化工业发展较快 ,现有煤焦油加工能力已达 180万 t / a .煤焦油加工工艺大多是考伯斯二次气化工艺的改进型.近十多年来 ,日本的煤焦油加工业已形成了集中化、大型化和现代化的产业体系 ,在煤焦油的精密分离和焦化产品的深度加工利用等方面取得了令人瞩目的成就.前苏联的煤焦油加工能力一直很强 ,单机装量年处理煤焦油的能力高达 60万 t,采用的多是一次气化单或双塔流程 ,精制的焦化产品约有 190种 ,其煤焦油分离效率仅次于德国.作为发展中国家 ,印度的煤焦油加工生产水平也较高 ,目前其生产量达 38万 t / a .印度在萘、苯、甲苯及二甲苯和酚的生产工艺方面取得了突出的成就 ,在甲苯、萘和蒽的催化氧化方面也作了大量的研究和开发工作.我国焦化工业起步不算太晚 ,但在近几十年内 ,焦化生产技术的改进与提高并不显著.目前我国仍采用 20世纪 50年代进口苏联的常压蒸馏一塔式、两塔式流程 ,每种馏分都需酸洗、碱洗脱酚 ,工艺流程长、能耗大、产品纯度低.以致我国不少的煤焦油下游产品如精萘还需进口.焦油加工前的处理
3.1焦油的均合为了保证连续焦油精馏装置正常工作.杂油和外来的焦油要按一定比例混合
3.2焦油的脱水焦油在蒸馏前必须脱水。脱水的焦油可以减少蒸馏系统的热耗，增加设备的生产能力，降低蒸馏系统阻力，改善馏分及沥青质量.减轻设备腐蚀。焦化厂回收生产粗焦油含水质觉分数约4%，并且水中还溶解许多无机盆类。水分子分散在焦油介质中形成了均相体系乳化液。焦油中还含有甲苯不溶物，喹啉不络物及其他小的分散微粒，这些微粒吸附在焦油与水的界面上，增加了乳化液的稳定性。采用在焦油贮槽内维持焦油温度在为70~80℃静置脱水.只能使焦抽水分脱至2~3%，而进人蒸馏系统的焦油含水要求小0.5%，因此，焦油还需要最终脱水。日前广泛采用的焦油最终脱水方法是在管式炉的对流段及一次蒸发器内进行.
粗焦油与脱水后经换热和预热的高温焦油混合入脱水塔、塔顶用轻油作回流。水与轻油形成的共沸混合物由塔顶逸出。经冷凝冷却后入分离器.分出水后的轻油返回至脱水塔:此法焦油水分可脱至0.1~0.2%日本等有采用加压脱水的方祛。
3.3焦油的脱盐焦油中所含的挥发性铵盐在最终脱水阶段即被除去。而占绝大部分的固定铵盐仍留在脱水焦油中。固定铵盐中氯化铵80%左右，其余为硫酸铵，硫氰化铁，亚硫酸铵及硫代硫酸铵等。当焦油被加热到220~250℃，这些铵盐将分解成游离酸和氨.如:
NH4Cl一NH3+HCl分解产生的酸将引起设备的严重腐蚀。因此，焦油在送入管式炉加热前，除了脱水还必须脱盐.焦油脱盐是在焦油进人管式炉一段最终脱水前加入碳酸钠溶

茚，有机化合物，一种稠环芳香烃，分子式为C9H8，是一个易燃的多环烃。它由苯环和环戊二烯稠合而成。茚是无色到淡黄色的液体，工业上主要用来生产香豆酮-茚热塑性树脂。 茚也被称为苯并茂，自然界中存在于煤焦油175-185°C 馏分中。可以通过钠和茚反应（茚是酸性的），然后水蒸气蒸馏将茚分离出来。 茚可以很快聚合。茚氧化得到邻羧基苯乙酸。 在乙醇钠存在下，茚和草酸乙酯缩合得到茚的草酸酯。碱金属存在下，茚与醛或酮反应则得到深色的亚甲基茚。

在高温焦油中，茚含量0.25%-0.3%，主要存在于沸点168-175℃的煤焦油及粗苯馏分中，在200℃以前的重质苯中，古马隆和茚约占40%以上。以重苯为原料在具有44块理论塔板的分馏塔上进行精馏，控制回流比为15-20：1，切取塔顶温度为180.6-181.1℃馏分，含茚可达98%。另一种提取茚的方法，是以重苯和粗溶剂的油为原料，用糠醛作为共沸剂进行共沸蒸馏。由于糠醛或者甲醛能与重苯中烃类组分形成共沸物，但与茚不形成共沸物，因而可制取纯产品。以重苯为原料在具有44块理论塔板的分馏塔上进行精馏，控制回流比为15-20：1，切取塔顶温度为180.6-181.1℃馏分，含茚可达98%。高温下将四氢萘通过SiO2/A12O3也可制得。
除少量用于有机溶剂和杀虫剂的中间体外，主要用于生产茚-古马隆树脂。可与其他液态烃混合作涂料溶剂。

这里讨论的是在1000℃左右煤炼焦所得的高温煤焦油，又称煤焦油。在常温下煤焦油是一种比重为1.17～1.19的黑褐色粘稠液体。
1．煤焦油的化学组成煤焦油组成中包括了如苯、苯酚这样低分子量的简单物质，直到甚至在真空下也不易蒸发的，分子量达数千的非常复杂物质，因此是一种十分复杂的混合物。煤焦油中有机化合物估计有一万种以上，已被鉴定的约有500多种。煤焦油化学组成特点是：①主要是芳香族化合物，而且大多数是两个环以上的稠环芳香族化合物，而烷烃、烯烃和环烷烃化合物很少；②还有杂环的含氧、含氮和含硫化合物；③含氧化合物如呈弱酸性的酚类以及中性的古马隆、氧芴等；④含氮化合物主要包括弱碱性的吡啶、喹啉及它们的衍生物，还有吡咯类如吲哚，咔唑等；⑤含硫化合物是噻吩、硫酚、硫杂茚等；⑥煤焦油中各种烃的烷基化合物数量甚少，而且它们的含量随着分子中环数增加而减少。 虽然煤焦油中组分是多种多样的，但大多数组分在煤焦油中的含量不高或极微。在煤焦油中含量占1％以上的组分只有13种。1. 2 国内外煤焦油工业的加工分离现状国外煤焦油加工工业较发达的国家有德国、日本、美国、英国、法国、意大利、前苏联等 ,虽然工艺有一定的差别 ,但都基于相同的原理.基本过程为:粗焦油→脱水→过滤脱渣→加碱液防设备腐蚀→负压下 150 - 180℃脱水脱轻油→无水焦油加热气化→二次闪蒸分离沥青→各种油蒸汽冷凝分成不同馏份[ 5 ].其中 ,德国和日本已将煤焦油的分离和利用的重点由高含量组分转向低含量组分 ,以从中获取合成精细化学品所需的高附加值成分 ,并且成功地开发出一系列先进的煤焦油加工新工艺.德国是最早利用煤焦油的国家.世界闻名的一些工艺流程几乎都是德国斯蒂尔公司和考伯斯公司设计的 ,投入相当大的力量 ,积极开发与完善加工新技术 ,扩大产品品种 ,提高产品的质量等级.目前 ,吕特格公司 (RutgersWerkeAG)的焦油加工能力为 150万 t / a,已能生产 500多种芳烃产品 ,煤焦油的化工利用率接近 60% ,位居世界之首.日本的焦化工业发展较快 ,现有煤焦油加工能力已达 180万 t / a .煤焦油加工工艺大多是考伯斯二次气化工艺的改进型.近十多年来 ,日本的煤焦油加工业已形成了集中化、大型化和现代化的产业体系 ,在煤焦油的精密分离和焦化产品的深度加工利用等方面取得了令人瞩目的成就.前苏联的煤焦油加工能力一直很强 ,单机装量年处理煤焦油的能力高达 60万 t,采用的多是一次气化单或双塔流程 ,精制的焦化产品约有 190种 ,其煤焦油分离效率仅次于德国.作为发展中国家 ,印度的煤焦油加工生产水平也较高 ,目前其生产量达 38万 t / a .印度在萘、苯、甲苯及二甲苯和酚的生产工艺方面取得了突出的成就 ,在甲苯、萘和蒽的催化氧化方面也作了大量的研究和开发工作.我国焦化工业起步不算太晚 ,但在近几十年内 ,焦化生产技术的改进与提高并不显著.目前我国仍采用 20世纪 50年代进口苏联的常压蒸馏一塔式、两塔式流程 ,每种馏分都需酸洗、碱洗脱酚 ,工艺流程长、能耗大、产品纯度低.以致我国不少的煤焦油下游产品如精萘还需进口.焦油加工前的处理
3.1焦油的均合为了保证连续焦油精馏装置正常工作.杂油和外来的焦油要按一定比例混合
3.2焦油的脱水焦油在蒸馏前必须脱水。脱水的焦油可以减少蒸馏系统的热耗，增加设备的生产能力，降低蒸馏系统阻力，改善馏分及沥青质量.减轻设备腐蚀。焦化厂回收生产粗焦油含水质觉分数约4%，并且水中还溶解许多无机盆类。水分子分散在焦油介质中形成了均相体系乳化液。焦油中还含有甲苯不溶物，喹啉不络物及其他小的分散微粒，这些微粒吸附在焦油与水的界面上，增加了乳化液的稳定性。采用在焦油贮槽内维持焦油温度在为70~80℃静置脱水.只能使焦抽水分脱至2~3%，而进人蒸馏系统的焦油含水要求小0.5%，因此，焦油还需要最终脱水。日前广泛采用的焦油最终脱水方法是在管式炉的对流段及一次蒸发器内进行.
粗焦油与脱水后经换热和预热的高温焦油混合入脱水塔、塔顶用轻油作回流。水与轻油形成的共沸混合物由塔顶逸出。经冷凝冷却后入分离器.分出水后的轻油返回至脱水塔:此法焦油水分可脱至0.1~0.2%日本等有采用加压脱水的方祛。
3.3焦油的脱盐焦油中所含的挥发性铵盐在最终脱水阶段即被除去。而占绝大部分的固定铵盐仍留在脱水焦油中。固定铵盐中氯化铵80%左右，其余为硫酸铵，硫氰化铁，亚硫酸铵及硫代硫酸铵等。当焦油被加热到220~250℃，这些铵盐将分解成游离酸和氨.如:
NH4Cl一NH3+HCl分解产生的酸将引起设备的严重腐蚀。因此，焦油在送入管式炉加热前，除了脱水还必须脱盐.焦油脱盐是在焦油进人管式炉一段最终脱水前加入碳酸钠溶

茚，有机化合物，一种稠环芳香烃，分子式为C9H8，是一个易燃的多环烃。它由苯环和环戊二烯稠合而成。茚是无色到淡黄色的液体，工业上主要用来生产香豆酮-茚热塑性树脂。 茚也被称为苯并茂，自然界中存在于煤焦油175-185°C 馏分中。可以通过钠和茚反应（茚是酸性的），然后水蒸气蒸馏将茚分离出来。 茚可以很快聚合。茚氧化得到邻羧基苯乙酸。 在乙醇钠存在下，茚和草酸乙酯缩合得到茚的草酸酯。碱金属存在下，茚与醛或酮反应则得到深色的亚甲基茚。

在高温焦油中，茚含量0.25%-0.3%，主要存在于沸点168-175℃的煤焦油及粗苯馏分中，在200℃以前的重质苯中，古马隆和茚约占40%以上。以重苯为原料在具有44块理论塔板的分馏塔上进行精馏，控制回流比为15-20：1，切取塔顶温度为180.6-181.1℃馏分，含茚可达98%。另一种提取茚的方法，是以重苯和粗溶剂的油为原料，用糠醛作为共沸剂进行共沸蒸馏。由于糠醛或者甲醛能与重苯中烃类组分形成共沸物，但与茚不形成共沸物，因而可制取纯产品。以重苯为原料在具有44块理论塔板的分馏塔上进行精馏，控制回流比为15-20：1，切取塔顶温度为180.6-181.1℃馏分，含茚可达98%。高温下将四氢萘通过SiO2/A12O3也可制得。
除少量用于有机溶剂和杀虫剂的中间体外，主要用于生产茚-古马隆树脂。可与其他液态烃混合作涂料溶剂。
