What is 2'-anilino-6'-[ethyl(3-methylbutyl)amino]-3'-methylspiro[isobenzofuran-1(3H),9'-[9H]xanthene]-3-one?
Chemical properties
6'-(Ethyl-(3-methylbutyl)amino)-3'-methyl-2'-(phenylamino)spiro[2-benzofuran-3,9'-xanthene]-1-one is an excellent coupler. The fluoran compound has two different crystal forms, one High melting point crystal, its melting point is in the range of 164-168℃; a low melting point crystal, its melting point is in the range of 145-156℃. Among these two different crystal forms, as a coupler in thermal or pressure-sensitive recording materials, the high-melting-point crystalline compound has the advantages of fast color development and not easy to fade.
What are the applications of Application
6'-(Ethyl-(3-methylbutyl)amino)-3'-methyl-2'-(phenylamino)spiro[2-benzofuran-3,9'-xanthene]-1-one is a kind of black fluoran thermopressure-sensitive dye, which is based on xanthene type. compound of the parent structure. It is usually a colorless or light-colored crystal, and when it comes into contact with a color developer (acid clay, bisphenol A, POB, etc.), it develops color with the cracking of the lactone ring in the molecule.
Flammability and Explosibility
Non flammable
Synthesis
6'-(Ethyl-(3-methylbutyl)amino)-3'-methyl-2'-(phenylamino)spiro[2-benzofuran-3,9'-xanthene]-1-one can be prepared from 2-[4-(N-ethyl-N-isopentyl)amino-2-hydroxy-benzoyl]sodium benzoate and 4-methoxy-2-methyldiphenylamine in concentrated sulfuric acid, hydrogen Reaction under the action of sodium.
