Which is the best method to synthesize benzoxazine?
Not only the traditional Mannich condensation methods of phenol, amine, and formaldehyde, but cycloaddition and other reactions are utilized to lead to the structural flexibility of benzoxazines. These methods are applicable to the monomer synthesis with alternative energy sources and to the synthesis of benzoxazine's analogue, naphthoxazine.
How are Benzoxazines obtained in the Mannich reaction?
Benzoxazines are obtained via Mannich reaction from phenols, formaldehyde, and amines [ 2 ]. Burke proposed the preparation of benzoxazine derivatives, 3,4-dihydro-1,3-2H-benzoxazines, in a single step from p -substituted phenols, formaldehyde, and primary amine in a molar ratio of 1:2:1, respectively ( Scheme 2) [ 3 ].
How is the stoichiometry of benzoxazine thermoset manipulated?
However, the stoichiometry is manipulated in a way to control the molecular weight to obtain polymers with rather smaller molecular weights that satisfy the required viscosity characteristics for a specific application. Benzoxazine thermoset resins are the reaction products of an amine, a phenol, and formaldehyde [1 ].
How is benzoxazine bearing trimethoxisilane ( 15 ) synthesized?
