Abstract
The invention discloses a kind of industrial production process of sodium sand, the granular size inequality that preparation technology of the prior art has the sodium sand prepared, cumbersome, the problem of time is long are solved.The present invention includes：(1) under nitrogen atmosphere protection, metallic sodium, dispersant and organic solvent are added into reactor；(2) metal sodium fusion is warming up to, operation cutter is sheared within the given period, and finished product is made after Slow cooling.Sodium sand prepared by the present invention active height, particle fine uniform, will not condense again, and whole preparation process have the time it is short, safe and reliable, it is reproducible the features such as.
Description
Technical field
The present invention relates to a kind of preparation method of sodium sand, and in particular to a kind of industrial production process of sodium sand.
Background technology
Metallic sodium is a kind of common industrial chemicals, in chemical reaction, in order to improve the activity and utilization rate of metallic sodium,
Sodium sand is generally prepared into, and the quality of sodium sand is relevant with its granular size and uniformity coefficient.Sodium sand is prepared in industry usual
It is that, by metal sodium fusion, by the way of mechanical agitation beats sodium, mixing speed is 40~50r/min, between more than 10 times
Have a rest stirring, then cool down, sodium sand is made.Sodium sand prepared by such a method, granular size is uneven, or even has big metallic sodium block to deposit
, easily condense, and it is cumbersome, and the time is long.
The content of the invention
The technical problems to be solved by the invention are：There is the particle for the sodium sand prepared in preparation technology of the prior art
Size is uneven, cumbersome, the problem of time is long, it is therefore intended that provide efficiently and safely to prepare active high, particle tiny
Uniformly, a kind of industrial production process for the sodium sand that will not be condensed again.
The present invention is achieved through the following technical solutions：
A kind of industrial production process of sodium sand, including：
(1) under nitrogen atmosphere protection, metallic sodium, dispersant and organic solvent are added into reactor；
(2) metal sodium fusion is warming up to, operation cutter is sheared within the given period, is made into after Slow cooling
Product.
The whole process of the industrial production process of sodium sand of the present invention is better than other sodium sand preparation methods in the industry, and method is：Gold
Belong to sodium under the protection of nitrogen atmosphere and in the organic solvent with micro dispersant, be warming up to fusing, clipped machine compared with
High speed shear is operated in the short time, is then slowly cooled to room temperature (25 DEG C or so) and is formed.The sodium that the inventive method is prepared
Sand particle fine uniform, grain diameter is 100~200 mesh.The present invention is small with operation difficulty, and the time is short, reproducible, can have
Active height is prepared efficiently and safely, will not occur to condense again, evengranular sodium sand.
Further, the addition of the dispersant is the 0.5wt% of metallic sodium, and the addition of organic solvent is metallic sodium weight
5 times of amount.
Further, the dispersant is polyvinyl resin.The organic solvent be toluene or ortho-xylene, meta-xylene,
Or paraxylene.
Preferably, the temperature of heating is 100~120 DEG C in the step (2).The rotating speed of the cutter is 10000r/
Min, the time for giving the period is 0.5~120min.
Further, the time of the Slow cooling is 150~180min, and the temperature after cooling is 25~40 DEG C.
The present invention compared with prior art, has the following advantages and advantages：
(1) operation difficulty of the present invention is small, and the time is short, reproducible；
(2) the sodium sand activity that prepared by the present invention is high, and particle fine uniform will not condense, and entirely prepare again
Process has the time short, the features such as safe and reliable.
