UV absorber-928 Chemical Properties,Uses,Production

Description

UV absorber-928(C29H35N3O) is a hydroxyphenyl benzotriazole UV absorber specially designed for high performance coating applications. UV absorber-928 provides efficiency to coating and light sensitive substrates due to its characteristic broad band absorption. With excellent solubility and high thermal and environmental performance, UV absorber-928 is particularly suitable for coatings exposed to high temperature curing processes, such as powder and coil coatings, or high environmental stress.

Uses

UV absorber-928 has broad absorption properties which can effectively protect coating and other photosensitive materials. UV absorber-928 has high solubility, high temperature resistant and good environmental durability and so on. UV absorber-928 is suitable for high performance coatings, especially suitable for powder coating and industrial and automotive coatings. UV absorber-928 can be enhanced when used in combination with a HALS stabilizer such as UV-292 or UV-123.

Chemical Synthesis

73936-91-1.jpg
In a dry argon atmosphere 0.150 g of oxime 5, 0.070 g of 1,2-phenylene diamine 1 and 0.150 ml triethyl-borate are dissolved in 4 ml dry THF and heated for 24 h at 60°C. After a TLC shows consumption of starting oxime the mixture is evaporated to dryness and the resulting residue purified by column chromatography (eluent: hexane - ethyl acetate: 10-1 vol/vol) to give 0.171 g (92 %) of the diazo-amine intermediate 6. Replacing the B(OEt)3 by 2.5 g of basic AI2O3 and the THF by 2 ml of xylene and heating this mixture to 140°C for 48 h gives after the usual work-up 0.089 mg of diazo compound 6 and 0.300 g of starting oxime 5. According the procedure given for the preparation of compound 4 in example 1, triazole 7 is obtained from 0.007 g (0.016 mmol) of intermediate amine 6 and 0.020 g (0.122 mmol) CuSO4 in 100% (0.007 g). In this comparative example, 7.73 equivalents of copper salt are used.
