Description

1. Factory
General requirements of workshop: *0m².
(1) Power source: 3 phase 5 line, about *0KW.
(2) Work time:*4hour/day,**0days/year. 
(3) Water supply: normal need. 

2. Producing details (main steps)
(1) To clean up the reaction kettle, close the feeding valve.
(2) In the reaction kettle to join the specified amount of solvent (ring n-hexane).
(3) To start the stir, add light magnesium oxide, mixing *0 min.
(4) Continuous joining weighing ***2 resin, stir to dissolve 3 ~ 4 h, until completely dissolved.
(5) After joining catalyst began to record the reaction time.
(6) In *4 ~ **0° C reaction 6 ~ *0 h. when the environment temperature is below **0 c beforehand reaction cannot take place, needs to be jacketed reactor in steam or hot water heating, maintain *0 ~ **0° C, 0.5 h to chelate reaction after the start stop heating.
(7) At predetermined reaction time arrival, feeding check reaction conditions.Particular way is to play to open the valve, the container released a small, close the valve immediately, such as reactant nodular condensed water immediately, that has reaction in good condition, if the pre-reaction to drops clicking underground stream, that bad pre-reaction should prolong the reaction time of 2 ~ 3 h, check again.check method can also be pre-reaction is placed within the beaker, dip in with stir bar flow observation condensation or situation.pre-reactant had better be finished as soon as possible, parking time is generally 7 ~ *0 d.
(8) Close sol kettle feeding valve.
(9) ethyl acetate, and 1/2 of solvent gasoline inventory.
(*0) To start the mixing, add the terpene resin and petroleum resin, mixing *0 ~ *0 min.
(*1) To join the specified amount of reactants, mixing rubber strip, airtight feeding mouth, continue to stir 5 ~ 6 h, parking, airtight stirring shaft rotation, parked overnight.
(*2) Start stirring, then stir in methylene chloride and the rest of the gasoline, stir *0 min, parking pour material 2 times.continue to stir for *0 min, parking airtight place 1 h.
(*3) discharge packing after inspection.Sol temperature of *5 ~ **0° C, general under **0 ° C neoprene can't completely dissolved, store a few will be layered, must turn up the heat in the sol.
