| titleOfInvention | 2,5-bis-(4-aminophenylthio)-1,3,4-thiadiasol or 2,5-bis)4-aminophenyl-sulfonyl)-1,3,4-thiadiasol as light stabilizers of cellulose acetate |
| abstract | The invention relates to heterocyclic compounds, in particular to 2,5bis (4-aminophenylthio) -1,3,4-thiadiazole or 2,5-bis (4-aminophenylsulfonyl) -1,3,4-thiaziazole use of cellulose acetate as light stabilizers. The goal is the creation of new, more active compounds. The preparation is carried out by condensation of equimolar amounts of 2,5-dimercapto-1,3,4-thiadiazole with 4-halide-nitrobenzene in an amide solvent medium, followed by reduction of the resulting dinitro compound. Yield,%: mp, ° C; gross-f-la: a) 85; [deg.] 25-227; Ci4HtzN4S3. b) 85; 191-193; COMMUNICATIONS New substances are more effective than the known 2, 6-dihydroxyphenylthio - 1,3,4-thiadiazole. 1 tab. |
