1、在反应釜中投入200升A、64公斤B，搅拌下加入5公斤C和53公斤D，通入蒸气，升温回流脱水。10小时后取样跟踪分析，保证B反应完全。降温到常温，加入500升水，搅拌半小时后静置15分钟，分层，分去下层水层，再用300升水水洗一次。升温脱出溶剂，当温度升至110ºC后关闭蒸气。减压蒸出剩余溶剂，蒸完后降温到室温。装桶，称重，取样分析。 [ Last edited by jmn on 2009-8-13 at 17:18 ] |

Ten hours later, take and analysis samples to ensure the complete reaction of B . Cool to room temperature, add 500 liters of water to the mixture and standing for 15 minutes after whisked for half an hour to be layered. Discard the lower water and then wash for the second time with 300 liters of water. Heat to remove the solvent by steam until the temperature rise to 110℃. Decrease the pressure to remove the residual solvent and put to the room temperature. Barrel, weight and then sample and analysis. |

Under mixing and adding 5 kg of C and 53 kg of D, the system was access to steam, and heated with recycled water to complete dehydration. After 10h, monitoring samples were made to ensure reaction B in completeness. Then, it was cooled to room temperature with adding 500 liters of water and stirring for half an hour. 15 minutes was necessary for standing, separation from water in low layer. 300 liters of water was used to wash the solution once. Solvent extrusion was made under high temperature. When temperature rose to 110oC steam, the valve was closed. After decompression to steam solvent remained, temperature of system was cooled to room temperature. Finally, loading into barrels, weighing and analysis of sample should be completed. |
