Abstract
The invention discloses a direct method used for preparing antimony pentoxide organosol. The direct method comprises following steps: step 1, antimonous oxide powder, water, ethylene glycol, and triethanolamine phosphate are delivered into a three-mouth flask provided with a magnetic stirring apparatus and a reflux condensation pipe, and an obtained mixture is heated to 95 DEG C with stirring of 200r/min; and step 2, oxidant hydrogen peroxide is added dropwise at an adding speed of 0.02ml/s using a constant-pressure funnel, after adding, oxidation reflux is carried out for 1.5h so as to obtain antimony pentoxide ethylene glycol sol. The direct method is simple; production period is short; energy consumption is low; particle distribution of obtained antimony pentoxide organosol particles is uniform; sol particle distribution degree is high; and the antimony pentoxide organosol is relatively stable.
Description
Technical field
The present invention relates to a kind of preparation method of compound, be specifically related to a kind of preparation method of antimony peroxide organosol.
Background technology
Colloidal antimony pentoxide has larger specific surface area, higher thermostability, stronger covering power and transparency and by as important fire retardant material, is widely used as the fire retardant of the products such as rubber.Antimony peroxide organosol can strengthen Diantimony Pentoxide Colloid and organic blending, can expand the range of application of colloidal antimony pentoxide.The production method of current antimony peroxide organosol mainly contains direct method and indirect method.
Summary of the invention
The object of the invention is to, provide a kind of direct method to prepare the method for antimony peroxide organosol, technique is simple, with short production cycle, consumes energy low, and the antimony peroxide organosol uniform particle produced, colloid is more stable.
Described direct method prepares the method for antimony peroxide organosol, and it comprises the following steps:
One, antimonous oxide powder, water, ethylene glycol and trolamine phosphoric acid salt are added in the there-necked flask with magnetic stirring apparatus and reflux condensing tube, under the stirring of 200r/min, be warming up to 95 DEG C;
Two, drip oxidant hydrogen peroxide by constant pressure funnel with the speed of 0.02ml/s, dropwise, continue oxidation back flow reaction 1.5h, obtain antimony peroxide ethylene glycol colloidal sol.
Direct method provided by the invention prepares the method for antimony peroxide organosol, and its beneficial effect is, technique is simple, with short production cycle, consume energy low, and the antimony peroxide organosol particle diameter produced is evenly distributed, colloidal particle degree of scatter is high, and colloid is more stable.
Embodiment
Below in conjunction with an embodiment, the method being prepared by direct method provided by the invention to antimony peroxide organosol is described in detail.
Embodiment
One, 3g antimonous oxide powder, 5g water, 9g ethylene glycol and 0.9g trolamine phosphoric acid salt are added in the 250ml there-necked flask with magnetic stirring apparatus and reflux condensing tube, under the stirring of 200r/min, be warming up to 95 DEG C;
Two, drip oxidant hydrogen peroxide 3.5g by constant pressure funnel with the speed of 0.02ml/s, dropwise, continue oxidation back flow reaction 1.5h, obtain antimony peroxide ethylene glycol colloidal sol.
