Description
Technical field
The present invention relates to a kind of technical field of fine, draw more particularly to a kind of dicetyl peroxydicarbonate ethylhexyl
Send out the Safe production technology of agent.
Background technique
Dicetyl peroxydicarbonate ethylhexyl (EHP) initiator, molecular formula C10H18O8 are that polyvinyl chloride resin production makes
Important auxiliary agent, the product are used not only for Production of PVC, are also largely used to other synthetic resin production.Due to the product
For peroxide, belong to hazardous chemical, so, manufacturing enterprise is constantly subjected to the monitoring of national departments concerned, the production
Technique comparative maturity, but produce that there are still security risks with storage and transport process.The domestic and international production enterprise is not yet
A set of practicable technical safety measures can thoroughly prevent the generation of production accident.Recently for over ten years, whether domestic
Enterprise, or the foreign major company joint with China, still have dodge quick-fried and fire incident, dodge every time it is quick-fried all can be to enterprise and duty
Work personal and property safety causes damages.The auxiliary agent enterprise of domestic production EHP peroxide is numerous, substantially using purchase second
Come what is produced, most enterprises do not make further research production technology and safety in production for side or third party's formula.According to investigation
It was found that the range that major accident occurs is as follows:
1, during producing peroxide, the accident as caused by artificial maloperation, the weight including adding raw materials is not allowed
Really, caused material reaction speed is accelerated, and temperature increases, and reacts out of control, also has due to lacking a sense of responsibility, operation error or
What overload operation occurred sleeps hilllock accident.Maloperation in order to prevent, some large enterprises under reaction kettle, be added to electronic weighting and
Alarm system.The equipment can preferably control the charging system of polymeric kettle, and the total weight by weighing material in reactor is protected
The accuracy of the material of addition has been demonstrate,proved, but has been inoperative for maloperation on duty.
2, in recent ten years, there is a situation where dodge production of the quick-fried and fire than workshop for peroxide initiator production freezer
Accident occurs more.It is various for tracing it to its cause, first is that the freezer of peroxide initiator build it is unreasonable, material barrel
It draws badly.In order to save money, many enterprise's freezers are not provided with the shelf for putting plastic barrel, and charging basket is piled up on the spot, charging basket stacking row
It embarks on journey to be aerated, once after storing material amount is big, ventilating duct ventilation quantity, which is reduced or is plugged, will result in freezing effect
Fruit is deteriorated, and generates dead angle, increases local temperature.EHP initiator is very active chemicals, begins to gasify higher than -5 DEG C
Volatilization is breakneck once reaching certain pressure will cause to dodge quick-fried.
3, since production technology is limited to, the initiator emulsion of some auxiliary reagent factories production is unstable, or even is layered, very
It is dangerous.The lo-tionized purpose of peroxide initiator is exactly for safety, and after initiator emulsion layering, protective layer does not have
Even if putting for a long time in freezer is also danger close, just more dangerous in material transportation, this is also initiator emulsion
Another reason for dodging quick-fried and fire.
In conclusion controllable production technology how is developed, it is effective to control being perfectly safe for peroxide production, with
And the safety of freezer how is carried out, it is to put cardinal task urgently to be resolved in face of our industries.
Summary of the invention
Aiming at the shortcomings existing in the above problems, the present invention provides a kind of dicetyl peroxydicarbonate ethylhexyl initiation
The Safe production technology of agent, makes it have that scrap build expense is low, material toxicity is low, is easy to purchase, cheap feature.
To solve the above-mentioned problems, the present invention provides a kind of dicetyl peroxydicarbonate ethylhexyl initiator, wherein by wrapping

8 parts of sodium.
Preferably, using 55 parts of chloro ester, 20 parts of hydrogen peroxide, dicetyl peroxydicarbonate is produced in 8 parts of reactions of sodium hydroxide
Ethylhexyl, by 65 parts of dicetyl peroxydicarbonate ethylhexyls and 35 parts of dodecane mixed dilutings at 65% oil-soluble peroxidating
Two diethyl hexylcarbonate initiator solutions.
A kind of Safe production technology of dicetyl peroxydicarbonate ethylhexyl initiator, wherein the following steps are included:
S10, after checking that equipment is in serviceable condition, it is spare to check that initiator stabilizer has squeezed into safety groove；
S20, deionized water is put into reaction kettle by process recipe, starts blender, added from feed opening by the caustic soda weighed up
Enter reaction kettle, opens freezing fluid valve, start and stir and reaction kettle is added in hydrogen peroxide, produce sodium peroxide；
S30, it is again turned on flowmeter, chloro ester is slowly added to reaction kettle, prepare EHP initiator stoste；
S40, EHP initiator is mixed with dodecane, produces 65% oil-soluble EHP initiator solution of content.
Preferably, in the step S30, quickly due to exothermic heat of reaction, once discovery temperature quickly increases, it is difficult to control
System, illustrates that charging rate is too fast, it is necessary to stops charging immediately, and under agitation, opens big freezing fluid valve and be quickly cooled down,
It is further continued for feeding after temperature falling.
Compared with prior art, the invention has the following advantages that
1, the present invention is in dicetyl peroxydicarbonate ethylhexyl Safety control system, using new stabilizer, knot
It closes and uses automatic temperature control system, can will stablize automatically in the case where material reaction is out of control in initiator warning temperature
Agent is added in reaction kettle, and preventing peroxide, the reaction was continued, prevents to occur to dodge quick-fried and fire, to guarantee in warning temperature energy and
When reaction kettle is added in stabilizer, use automatic and spare charging systems double manually, ensure that the peace of EHP initiator production
Entirely.
It 2, is true after the present invention uses new stabilizer system in dicetyl peroxydicarbonate ethylhexyl production process
Production safety is protected, stabilizer slot will fill liquefied stabilizer for a long time, in the case where not using for a long time, every 3-5 displacement one
Secondary, the technology is low with scrap build expense, material toxicity is low, is easy to purchase, cheap feature.
3, the manufacturing cost of New-style refrigeration house of the present invention is cheap, and it is good to compare old-fashioned freezer flame retardant property, by using sunlight screen
The surface temperature that exterior wall is reduced with sunshade keeps the cooling effect of freezer more preferable, and energy consumption is lower, has from cooling and safety
High advantage, and by the increase ventilation shelf in freezer, air cooling effect is improved, it is quick-fried to the sudden strain of a muscle for preventing EHP initiator, it keeps away
Exempt from personal accidental injury and property loss is significant.
In conclusion the present invention passes through many years experimental selection toxicity high-efficiency stabilizing agent that is low, at low cost, being easy to buying,
The higher initiator freezer of safety is designed, the safety problem of EHP initiator production and storage and transportation is solved, such as pushes away at home
Extensively, it will the safety for substantially improving domestic EHP initiator dangerous material production has important economic value and social value；
For the stability of emulsion for improving EHP initiator, the present invention does not use old solid initiator, using new emulsifier body
System, combine using the pure and mild alkoxylate phenol resin of alkylaryl polyether with polyvinyl alcohol stabilizer produce it is more stable
EHP initiator emulsion, initiator validity period were increased to 12 months from 6 months of professional standard, and reduced the flake of resin
And crystal point, improve the quality of resin.
