Fischer-Tropsch (Fischer-Tropsch) wax is a methylene polymer, is an alkane polymer synthesized from hydrocarbon-based synthesis gas or natural gas, and mainly depends on high-quality and cheap raw materials in the coal chemical industry to carry out iron-based or cobalt-based synthesis. Light stability is an important indicator in Fischer-Tropsch wax products; the unstable components in the compounds and aromatic hydrocarbon, olefin and alkane substances are easy to oxidize under the action of ultraviolet rays and heat, so that the Fischer-Tropsch wax is darkened and the use value is reduced. The Fischer-Tropsch wax has wide application in the industries of food, medical treatment, chemical industry and the like, and in the continuous development of various industries, the requirements on the variety and quality of the Fischer-Tropsch wax are higher and higher, a plurality of varieties are derived continuously, and the Fischer-Tropsch wax contains a small amount of isoparaffin, aromatic hydrocarbon, olefin and a trace amount of S, N, O compound. Due to the comprehensive action of factors such as light, heat, oxygen and the like, the Fischer-Tropsch wax is gradually oxidized and deteriorated, the color becomes dark, and the service performance of the Fischer-Tropsch wax is influenced.
The existing Fischer-Tropsch wax ultraviolet light stability chromaticity determination is that a Fischer-Tropsch wax sample after ultraviolet light stability characteristic test is melted, then is injected into a cuvette, is put into a colorimetric box, is irradiated by a fluorescent lamp, is compared with a color palette through a visual inspection lens, and is adjusted to be consistent with the color of the sample, and the color number of the colorimetric palette is the color number of the Fischer-Tropsch wax.
The fatal shortcoming of current ultraviolet ampere color test is: (1) because the cuvette is placed at the normal temperature; after the ultraviolet light stability detection result, the sample is in a liquid state and is transferred to a colorimetric dish for chromaticity test, the color change degree difference is large, and the color of the sample is also darkened in the transfer process. (2) The time between the two detection devices also affects the sample results.
