Title (EN) 2,2-DIALKYL-2H-IMIDAZOLE-1-OXIDES AND METHOD OF OBTAINING THEM
(FR) OXYDES DE 2,2-DIALKYLE-2H-IMIDAZOLE-1 ET LEUR PROCEDE D'OBTENTION
Abstract:
(EN) New compositions: 2,2-dialkyl-2H-imidazole-1-oxides have general formula (I), where R1 = C6H5, CH3, CH=NOH, pO2NC6H4, M-O2NC6H4; R2 = CH3, CH2CH2CH3; R3 = CH3, (CH2)7CH3, CH2COOC2H5, CH2CH2COOCH3, CH2CH2COOH, CH2CH2CH3, (CH2)8CH3. The method for obtaining said compositions consists in that hydroximinomethylketones of general formula (II), where R1 = C6H5, CH3, CH=NOH, p-O2NC6H4, are interacted with aliphatic ketones of general formula R2-CO-R3, where R2 = CH3, CH2CH2CH3; R3 = CH3, (CH2)7CH3, CH2COOC2H5, CH2CH2COOCH3, CH2CH2COOH, CH2CH2CH3, (CH2)8CH3, and with ammmonium acetate. The molar ratio of components is 1:3.5-20:1.6-6.0, respectively. The process is carried out in the medium of acetic acid at a temperature of 20-100 °C. As a result a reaction mass is obtained containing the desired product which is then extracte.
(FR) Nouvelles compositions: oxydes de 2,2-dialkyle-2H-imidazole-1 ayant la formule générale (I), dans laquelle R1 = C6H5, CH3, CH=NOH, p-O2NC6H4, M-O2NC6H4; R2 = CH3, CH2CH2CH3; R3 = CH3, (CH2)7CH3, CH2COOC2H5, CH2CH2COOH3, CH2CH2COOH, CH2CH2CH3, (CH2)8CH3. Le procédé d'obtention desdites compositions consiste en ce que les hydroximinométhylcétones de la formule générale (II) (dans laquelle R1 = C6H5, CH3, CH=NOH, p-O2NC6H4, M-O2NC6H4) sont mises en interaction avec des cétones aliphatiques de la formule: R2-CO-R3 (dans laquelle R2 = CH3, CH2CH2CH3; R3 = CH3, (CH2)7CH3, CH2COOC2H5, CH2CH2COOCH3, CH2CH2COOH, CH2CH2CH3, (CH2)8CH3) et avec de l'acétate d'ammonium. Le rapport molaire des composants est 1:3,5 à 20:1,6 à 6,0, respectivement. Le procédé est mis en ÷uvre dans le milieu d'acide acétique à une température comprise entre 20 et 100 °C. On obtient, en résultat, une masse de réaction contenant le produit désiré, lequel est ensuite extrait.
