⑷ 求实验室减压蒸馏装置图
实验室减压蒸馏装置图如下图所示:
实验原理
1.减压蒸馏适用对象
在常压蒸馏时回未达沸点即已答受热分解、氧化或聚合的物质
2、减压下的沸点
(1)通常液体的沸点是指其表面的蒸气压等于外界大气压时的温度;
(2)液体沸腾时温度是与外界的压力相关的,即外界压力降低沸点也降低;
(3)利用外界压力和液体沸点之间的关系,将液体置于一可减压的装置中,随体系压力的减小,液体沸腾的温度即可降低,这种在较低压力下进行蒸馏的操作被称为减压蒸馏。
注意事项
1.真空油泵的好坏决定于其机械结构和真空泵油的质量,如果是蒸馏挥发性较大的有机溶剂,其蒸气被油吸收后,会增加油的蒸气压,影响泵的抽真空效果;如果是酸性的蒸气,还会腐蚀泵的机件;
另外,由于水蒸气凝结后会与油形成浓稠的乳浊液,破坏了油泵的正常工作。因此,在真空油泵的使用中,应安装必要的保护装置。
2.测压计的作用是指示减压蒸馏系统内部的压力,通常采用水银测压计,一般可分为封闭式和开口式两种。使用时必须注意勿使水或脏物侵入测压计内。水银柱中也不得有小气泡存在。否则,将影响测定压力的准确性。
⑸ 蒸馏装置示意图及仪器名称
(m)蒸馏时,温度计用于测量分离出的馏分温度,即被蒸馏物质的沸点,温度回计水银球应处在蒸馏烧答瓶的支管口附近,冷凝管应从个口进水,上口出水,以保证水充满冷凝管,起到充分冷凝的作用,图中温度计水银球插入太深,冷却水进出口标反了,
故答案为:①温度计水银球插入太深;&上bsp;②冷却水进出口标反了;
(中)蒸馏装置中的主要仪器有蒸馏烧瓶、冷凝管、牛角管、锥形瓶,酒精灯,a为蒸馏烧瓶,B为冷凝管,
故答案为:蒸馏烧瓶;冷凝管
(m)蒸馏的原理为根据混溶的液体的沸点不同进行分离各成分,所以把蒸馏烧瓶固定在铁架台上,在蒸馏烧瓶上装好分液漏斗,连接好导气管,应先检查装置的气密性,若装置不漏气,再加液体反应物开始反应,制取气体,
故答案为:检验装置的气密性;
(了)实验时A中除了加入要分离的混合物溶液外,为防止液体暴沸,应加碎瓷片,
故答案为:沸石(或碎瓷片);防止液体暴沸;

⑻ 化工:蒸馏塔、精馏塔的图纸中,管道用A、D、E、R、L、N、P、Q等英文符号,这些英文符号代表管道的什么
设备图纸的英文字母表示的是管口符号,没有特定的字母代表哪种观点。
字母一般都是随便设的,应该还有一个管口表啊
⑼ 精馏塔英文简介
以下是翻译你写的精馏塔简介:Distillation is a distillation tower for vapor-liquid contact device, also known as distillation. A plate column and packed column types. According to mode of operation are divided into continuous distillation and batch distillation. Steam from the bottom of the column entry, and the decline in liquid countercurrent contact with the two in contact, the drop in the volatile liquid (low boiling point) components is continuously transferred to the steam. The difficulty of steam volatile (high boiling) component continued to decline in the transfer of liquid, steam the closer the top of the tower, the higher the concentration of its volatile components, while the decline in the closer tower bottom liquid, its hard to be more volatile components rich set, to achieve component separation. Steam rising from the top of the tower into the condenser, the liquid part of the condensate as reflux liquid to return into the distillation tower, the rest is removed as distillate. Tower bottom outflow of liquid, some of which into the reboiler, thermal evaporation, the steam back to tower, and the other part of the liquid as resia release.
