    不锈钢冷凝器具有耐高温、耐腐蚀、生产能力强等优点,广泛用于医药、饮料、化工、颜料、树脂、科研等工业部门。冷凝器是融合了反应容器,反应条件控制系统,原料进料、产品导出系统的一类生产或实验器械。不锈钢冷凝器操作要点:

    Stainless steel condenser has the advantages of high temperature resistance, corrosion resistance and strong production capacity. It is widely used in pharmaceutical, beverage, chemical industry, pigments, resins, scientific research and other industrial sectors. Condenser is a kind of production or experimental equipment which integrates reaction vessel, reaction condition control system, raw material feeding and product export system. Operating Points of Stainless Steel Condenser:

    1. 开控制台电流开关前,应先使搅拌开关、调速加热开关调到零。

    1. Before opening the current switch of the console, the stirring switch and the speed regulating heating switch should be set to zero.

    2. 投料前用蒸馏水冲洗高压釜内壁、搅拌及接合面,接合面冲洗后要再用棉花或绸布蘸乙醇擦净,再慢慢合上上盖,以免撞伤接合面。

    2. Wash the inner wall of autoclave, mix and joint with distilled water before feeding. After washing, clean the joint with cotton or silk cloth dipped in ethanol, and then close the cover slowly to avoid bumping into the joint.

    3. 上螺丝时一定要对号入座,且用扭力扳手成十字形对称地上,以避免受力不均。螺丝不要一次扭到位,应逐步加力对称上紧。

    3. When the screw is put on, it must be seated in the right place, and the torsion wrench should be crossed symmetrically to avoid uneven force. The screw should not be twisted in place at one time, but should be tightened symmetrically step by step.

    4. 螺丝上紧后,先用机械泵抽真空,然后反复通氮气二至四次,将釜内空气排尽,再抽真空,通入氢气,开搅拌,升温,正常操作。

    4. After the screw is tightened, the vacuum is pumped by a mechanical pump first, and then the nitrogen gas is repeatedly ventilated for two to four times. The air in the kettle is exhausted, and then the vacuum is pumped into the hydrogen gas, the stirring is opened, the temperature is raised, and the normal operation is carried out.

    5. 反应毕,停止搅拌,将釜内残余氢气抽尽,再通入氮气,放空,拧开螺丝取样。

    5. After the reaction, stop stirring, exhaust the residual hydrogen in the kettle, then inject nitrogen, empty and unscrew the screw for sampling.

    6. 5L冷凝器不耐强酸,反应液中禁用盐酸、硫酸、硝酸等强酸。

    6.5L condenser does not tolerate strong acid. Hydrochloric acid, sulfuric acid, nitric acid and other strong acids are forbidden in the reaction solution.

    7. 冷凝器附近,禁止有产生火花的作业,禁止穿钉子鞋操作。

    7. Around the condenser, spark-producing operations are prohibited and nail-shoe-wearing operations are prohibited. 不锈钢冷凝器使用详细步骤

    Detailed Steps for Use of Stainless Steel Condenser

    1、冲洗釜

    1. Flushing kettle

    2、开釜投入底物

    2. Opening the kettle and putting it into the substrate

    3、关釜,溶解在溶剂中的钯/炭催化剂通过漏斗加料装置加入釜中,取下进料装置,接上氢气铜管,关闭进气口和出气口

    3. Close the kettle, the palladium/carbon catalyst dissolved in the solvent is added into the kettle through funnel feeding device, the feeding device is removed, the hydrogen copper tube is connected, and the intake and outlet are closed.

    4、关闭减压阀,全部打开氢气瓶总阀

    4. Close the pressure relief valve and open the hydrogen cylinder main valve

    5、调节减压阀为18个大气压

    5. Adjust the pressure relief valve to 18 atmospheric pressures

    6、打开进气口,调节釜内压力为5公斤左右,关闭进气口,打开出气口,调节釜内压力约为2公斤左右,关闭出气口;再次打开进气口,调节釜内压力为5公斤左右,关闭进气口,保持约15分钟,看看釜压有没有变化,考察釜的气密性;打开出气口,调节釜内压力为2公斤,关闭出气口;再次打开进气口调节压力为加氢压力(约为15公斤),打开搅拌,稍许升高釜内温度,因为放热后面反应温度升高须用夹套冷却水调节温度,间隔记录温度和压力的变化,直至压力不再变化为止。(在加氢过程中,应不断地补加氢气,具体的补加程序为:压力从15降到10 ,打开进气阀调节釜内压力重新为 15 公斤 ,关闭进气阀,同时记录补加的氢气量)

    6. Open the intake port, adjust the pressure in the kettle to be about 5 kg, close the intake port, open the outlet, adjust the pressure in the kettle to be about 2 kg, close the outlet; Open the intake port again, adjust the pressure in the kettle to be about 5 kg, close the intake port for about 15 minutes, see if the pressure of the kettle has changed, check the tightness of the kettle; Open the outlet, adjust the pressure in the kettle to be about 2 kg. Close the outlet; reopen the inlet to regulate the pressure for hydrogenation (about 15 kg), open the stirring, slightly raise the temperature in the kettle, because after exothermic reaction temperature rise must be adjusted by jacket cooling water, and record the temperature and pressure changes at intervals until the pressure no longer changes. (In the process of hydrogenation, hydrogenation gas should be continuously supplemented. The specific procedures are as follows: the pressure is reduced from 15 to 10, the pressure in the regulating kettle of the intake valve is re-opened to 15 kg, the intake valve is closed, and the amount of hydrogen added is recorded.)

    7、反应完毕,关闭氢气瓶总阀,打开釜的出气阀,调节釜内压力为3公斤左右,关闭出气阀,打开进气阀,再关闭进气阀,打开出气阀,调节釜内压力为3公斤左右,关闭出气阀,直至减压阀的压力值达到安全,取下进气装置。

    7. After the reaction, close the main valve of the hydrogen cylinder, open the outlet valve of the kettle, adjust the pressure in the kettle to about 3 kg, close the outlet valve, open the inlet valve, then close the inlet valve, open the outlet valve, adjust the pressure in the kettle to about 3 kg, close the outlet valve until the pressure value of the pressure relief valve reaches safety, and remove the intake device.

    8、接上出料装置,打开进气阀把里面的料液压出来。

    8. Connect the discharging device and open the intake valve to press the material out.
