Abstract

The invention discloses a detection method of purity of antimony pentafluoride products. The detection method comprises the following steps of: (i) preparing a sample, including sampling, solidifying and hydrolyzing; (ii) quantifying trivalent antimony, namely utilizing an oxidation-reduction titration method to measure the trivalent antimony; (iii) detecting total content of antimony, namely using an inductively coupled plasma emission spectrometer, selecting 206.836nm as an analytical line used for measuring, and detecting the content of total antimony elements in hydrolysate; (iv) calculating the content of pentavalent antimony, namely subtracting the content of the trivalent antimony from the total content of the antimony elements to obtain the content of the pentavalent antimony; andthrough calculating, obtaining the purity of the antimony pentafluoride products. The detection method is simple and convenient and feasible and is convenient for operation, the measurement accuracy is high, and the method is particularly suitable for detecting the purity of the antimony pentafluoride products prepared by fluoride and simple substance antimony as raw materials.

Description

Technical field

[0001] The invention belongs to a method for detecting the purity of antimony pentafluoride products, and specifically relates to a method for detecting the purity of antimony pentafluoride products prepared by using fluorine gas and elemental antimony as raw materials. Background technique

[0002] Antimony pentafluoride (SbF 5 ) Is a high-energy fluorinating agent. It is the main component of the catalyst in perfluoroalkyl iodide (PFAIS). It is the main product to replace chloroalkane refrigeration. It is the catalyst for the production of refrigeration difluoromethane. It is the production of new explosives and jets. The catalyst of fuel is the catalyst of certain drugs (such as fluoromethyl quinoline, etc.), the additive of anti-cancer drugs, and the intermediate of special membranes, plastics, lubricants, medical anesthetics, blood substitutes, etc. It is an improvement Catalyst for the production of gasoline-quality isobutylation.

[0003] At present, there a...
