Abstract
The invention relates to a method for preparing chrome resorcin-ate. The method includes the following steps of 1, the salt forming reaction step, wherein resorcin acid, chromic oxide, initiators and water are put into a reaction kettle in the molar ratio of 1:15:0.65-0.825:0.2-0.5, the mixture is heated to 70 DEG C to 80 DEG C while stirring, reacting is carried out for 5 h to 7 h to enable carbon dioxide to overflow, and the chrome resorcin-ate is obtained; 2, the drying step, wherein the chrome resorcin-ate crystals obtained in the step 1 are centrifugally separated to obtain granular chrome resorcin-ate, the granular chrome resorcin-ate is placed into a drying sieve to be dried in a drying box, sieving is carried out after drying, and the finished chrome resorcin-ate is obtained. According to the method, during material putting, sodium resorcin-ate is replaced by the resorcin acid, chromium sulfate is replaced by the chromic oxide, and the obtained product is only the chrome resorcin-ate; the product is single, high in purity, granular and easy to dry after being separated, the obtained crystal product does not need to be smashed, and a large amount of dust is avoided.
Description
Technical field
The invention belongs to field of organic compound preparation, relate to the sad chromium of mine-mooring cable, the preparation method of the sad chromium of especially a kind of mine-mooring cable.
Background technology
In organic additive, the sad chromium of mine-mooring cable, as the effective chrome mineral additive of one, more and more comes into one's own, is with a wide range of applications.The usual production method of the sad chromium of mine-mooring cable utilizes mine-mooring cable Sodium octoate and chromium sulphate to react, the product obtained is thick thing, further difficult treatment, be difficult to purify, this type of preparation method's Problems existing: 1, in further treatment step, repeatedly crystallization, need crystallizer be increased, equipment is many, complicated, production cost is high, be difficult to reduce production cost; 2, finished product purity is low, and dust is a lot, and enterprise is difficult to a large amount of production, is unfavorable for the development of enterprise and the raising of economic benefit.

Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art part, provide one can save facility investment, reduce costs, the product obtained, without the need to repeatedly crystallization, avoids the preparation method of the sad chromium of mine-mooring cable of the work of a large amount of repetitions.
The technical scheme that technical solution problem of the present invention adopts is:
A preparation method for the sad chromium of mine-mooring cable, step is as follows:
(1) salt-forming reaction step: mine-mooring cable is sad, chromic oxide, initiator, hydromassage you drop in reactor than 1:15:0.65 ~ 0.825:0.2 ~ 0.5,70 ~ 80 DEG C are heated to while stirring, react 5 ~ 7 hours, carbonic acid gas is overflowed, obtain the sad chromium of mine-mooring cable;
(2) baking step: by step (1) in the crystallization of mine-mooring cable sad chromium, the centrifugation that obtain obtain the sad chromium of particulate state mine-mooring cable, sad for particulate state mine-mooring cable chromium is placed in dry sieve and dries in loft drier, sieve after oven dry and obtain the sad chromium of finished product mine-mooring cable.
And described initiator is for having C

mh
m+2[n=1,2,3,4,5,6; M=1,2] aminated compounds.
And, step (2) described in dry sieve be the stainless steel dry sieve of breathing freely up and down.
Advantage of the present invention and positively effect are:
1, present method is in feeding intake, and uses mine-mooring cable sad replacement mine-mooring cable Sodium octoate, uses chromic oxide to replace chromium sulphate, the product obtained only has the sad chromium of mine-mooring cable, and product is single, purity is high, in particulate state, be easy to dry after separation, the crystalline product obtained, without the need to pulverizing, avoids a large amount of dust.
2, the granular product that obtains of present method, is easy to dry, decreases protection and equipment, saved facility investment, reduced running cost.
3, present method has easy feature convenient and simple for operation, is convenient to realize suitability for industrialized production, enhances productivity.
4, present method in process of production, uses chromic oxide and initiator, ensures to obtain granular product, be beneficial to drying, need not pulverize, avoid dust, simultaneously present method has and realizes simple, easy to operate feature, has saved the investment of production unit, has improve production efficiency.
5, the dry sieve that present method uses is the stainless steel dry sieve of breathing freely up and down, make the sad chromium of mine-mooring cable when drying good permeability, moisture evaporation soon, easily dry.
