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.
