Description
Technical field
The present invention relates to chemical technology fields, and in particular to a kind of xanthate vacuum preparation facilities.
Background technique
Xanthate scientific name alkyl xanthates or alkyl dithiocarbonate, there are commonly ethyl xanthate, butyl xanthate, isopropyls
Base xanthate, Isobutylxanthic acid, amyl group xanthate, hexyl xanthate etc..
Xanthate purposes is very wide, and rubber industry is used as vulcanization accelerator, makees copper, nickel etc. with ehtyl potassium xanthate in analytical chemistry
The precipitating reagent and colorimetric reagent of metal ion, use in metallurgical industry xanthate as from solution precipitate cobalt, nickel reagent, cellulose
Sodium xanthogenate is to staple fibre processed.Xanthate is sulfide mineral collector most widely used at present, and the estimation whole world is for flotation
All kinds of xanthate amounts are every year in tens of thousands of tons to nearly 100,000 tons.
Xanthate has pungent odour, and toxic, ignition, hygroscopic deliquescence, property is unstable, has oxidisability.
There are many synthesis technologies, as direct synthesis technique, aqua-solution method, diluent method, portion of diluent method, alcohol excess method, steaming process,
Alkali metal alcoholate method etc..It is Chinese generally to be produced using direct synthesis technique, it is completed in kneading machine, by the alcohol and hydrogen-oxygen of theoretical proportions amount
Change sodium powder end to interact, be slow added into carbon disulfide, carries out xanthan acidification response, synthesis xanthate is obtained, through dryly dry
Xanthate；Or also use " anti-feeding method ", i.e., first alcohol is mixed with carbon disulfide, then hydroxide sodium powder is slowly controlledly added
Xanthate is made in end.
Entire chemical reaction in xanthate production process is completed in kneading machine, although traditional kneading machine is a close
The space of envelope, but appoint in the reaction kettle of kneading machine and so have large quantity of air, it is yellow during carrying out xanthate production reaction
Medicine, oxidative ionic are easy to react with water, oxygen or the carbon dioxide etc. in air, influence the production of xanthate, lower xanthate
Purity, while traditional agitating knife for kneading machine length is longer, and when heating increases motor load, due to stirring knife setting angle problem,
After kneading machine is added in sodium hydroxide powder, the state change of reactant is complex, becomes solid powder from pulpous state, half solid fraction
End, it is necessary under strong stirring can be just that agent is uniformly mixed, and traditional kneading machine sodium hydroxide cannot in time uniformly with
Material mixing will cause local reaction quickening, be unable to fully stir in time, is not easy to reaction and completes.
Sodium hydroxide as raw material is all that the mode of pickaback hand rest is leaned on to be manually fed into grinding machine, by block-like sodium hydroxide
It carries out being ground into sodium hydroxide powder, sodium hydroxide can generate amount of heat, and sodium hydroxide with after the contact with moisture in air
With characteristics such as extremely strong corrosivity, a large amount of sodium hydroxide dust are easy to produce during carrying, working environment is poor, Yi Zao
At occupational disease, the large labor intensity of worker needs several workers while carrying, delivering sodium hydroxide, and working efficiency is low, manually
It is at high cost, the problems such as employee turnover is big.
Xanthate preparation synthesis process in many places equipment need to cool down, and traditional xanthate refrigerant wetting system cold-storage ability compared with
Small, water supply is limited, needs to be equipped with more sets or is independently equipped with a set of cooling equipment for required equipment, increases the investment of equipment
Expense, equipment dispersion, is unfavorable for managing, and increases maintenance and maintenance load, while the refrigerant of traditional xanthate refrigerant wetting system
Coolant-temperature gage fluctuation is larger, and xanthate synthesis process needs effective control synthesis temperature, this needs to be adjusted by chilled water
Control, chilled water temperature is inaccurate or fluctuates larger, is unfavorable for the synthesis of xanthate, reduces the purity of xanthate.
Invent a kind of preparation method of xanthate urgently to solve above-mentioned technical problem.
