The beneficial effects of the utility model are: provide a kind of novel dichlor production equipment; this device have rational in infrastructure, produce quick, easy and simple to handle, low without high-temperature high-voltage reaction, energy consumption, environmental protection, finished product goes out rate advantages of higher; the yield of the finished product dichlor can reach more than 80.0%, product purity can reach more than 98.0%, and product is mainly used as the protective material of the weedicides such as alachlor, acetochlor, propachlor, EPTC.
Accompanying drawing illustrates:
If Fig. 1 is Structure and energy FB(flow block) of the present utility model.
Embodiment
The particular content using this new device to produce dichlor most preferred embodiment is further illustrated below in conjunction with accompanying drawing:
1. the metering of whole reaction counts by weight percentage, first ethanol is sent into scale tank 1 by the import 5 be arranged on scale tank 1, accurate-metering is be provided with the first impeller pump between scale tank 1 and chemical reaction kettle 2 and chemical reaction kettle 2 sent into by pipeline 6 by being arranged at after 54% of reactant weight, again liquid caustic soda is sent into scale tank 1 by same import, accurate-metering is be provided with the first impeller pump between scale tank 1 and chemical reaction kettle 2 and chemical reaction kettle 2 sent into by pipeline 6 by being arranged at after 18% of reactant weight, 3rd sends into scale tank 1 dichloro acetamide by same import, and accurate-metering is be provided with the first impeller pump between scale tank 1 and chemical reaction kettle 2 and chemical reaction kettle 2 sent into by pipeline 6 by being arranged at after 14.7% of reactant weight, now the material in chemical reaction kettle being sent into cool brine by the import 8 be arranged on chemical reaction kettle 2 interlayer while stirring in the interlayer of chemical reaction kettle 2 makes the temperature of liquid in chemical reaction kettle be down to less than-5 DEG C, cooling is discharged by circulating brine outlet 9 after circulating brine temperature uprises, now start to pass through slowly the hexalin import 7 be arranged on chemical reaction kettle 2 in chemical reaction kettle 2, drip that to account for gross weight be 13.3% hexalin, time for adding is 6 hours, dropping temperature controls below 0 DEG C, dropwise maintenance 0 DEG C to stir 0.5 hour, then temperature of reaction is elevated to 75-80 DEG C of backflow 4 hours, sampling detects qualified rear reaction and terminates, be cooled to normal temperature and obtain solidliquid mixture.
2. solidliquid mixture is sent into after separating centrifuge 3 carries out solid-liquid separation by being arranged at the first shurry pump between chemical reaction kettle 2 and separating centrifuge 3 and pipeline 10, liquid portion is discharged by the liquid exit 11 be arranged on separating centrifuge 3, solid part sends into dryer 4 by the first transfer roller 12 be arranged between separating centrifuge 3 and dryer 4 dries, obtain product, product by being arranged at product outlet 13 discharging on dryer 4, the finished product dichlor yield is greater than 80.0%, purity is greater than 98.0%.
