Versuchsvorschrift

To a 250 ml 3-necked flask was added 0.5 gm 2,5-thiophenedicarboxaldehyde, 30 ml acetic acid, 5.6 gm 2-ethylhexylesterphenyl hydroxylamine 3 and stirred for 20 hrs at room temperature. To the reaction mixture, 100 ml water was added and the mixture was filtered. The filtered product was washed with water and dried. A yield of about 1.6 gm of 2, 5-thiophene bis-2-ethylhexylesterphenyl dinitrone of Ex.2 was obtained with a HPLC purity of 98% (DSC: 205° C.).
