Description
Technical field
The present invention relates to chemical technology fields, and in particular to a kind of xanthate vacuum preparing system.
Background technology
Xanthate scientific name alkyl xanthates or alkyl dithiocarbonate, it is common to have ethyl xanthate, butyl xanthate, isopropyl
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, in metallurgical industry by the use of 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 thousand of tons to nearly 100,000 tons.
Xanthate carries 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, carry out xanthan acidification response, obtain synthesis xanthate, through it is dry must be dry
Xanthate；Or also first mixed alcohol with carbon disulfide using " anti-feeding method ", then slowly controlledly add in hydroxide sodium powder
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 xanthate production reaction is carried out
Medicine, oxidative ionic easily react with water, oxygen or the carbon dioxide in air etc., 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 sodium hydroxide powder adds in kneading machine, 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 can cause local reaction to accelerate, and can not fully stir in time, be not easy to reaction and complete.
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
Sodium hydroxide powder is ground into, sodium hydroxide is with that after the contact with moisture in air, can generate amount of heat, and sodium hydroxide
With characteristics such as extremely strong corrosivity, a large amount of sodium hydroxide dust are easily generated during carrying, working environment is poor, Yi Zao
Into occupational disease, the labor intensity of worker is big, it is necessary to which several workers carry, deliver sodium hydroxide simultaneously, and work efficiency is low, manually
It is of high cost, the problems such as employee turnover is big.
Xanthate prepare building-up 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 to be covered, it is necessary to be equipped with more or is independently equipped with a set of cooling device for required equipment, increases the input of equipment
Expense, equipment are disperseed, and are unfavorable for managing, and increase maintenance and maintenance load, while the refrigerant of traditional xanthate refrigerant wetting system
Coolant-temperature gage fluctuation is larger, and xanthate building-up process needs effective control synthesis temperature, this needs to be adjusted by chilled water
