New Advances in Chemical Research in 2021. In heterogeneous catalysis, catalysts provide a surface to which reactants bind in a process of adsorption. The reactant in an enzyme-catalyzed reaction is called a substrate. 108-32-7, Name is 4-Methyl-1,3-dioxolan-2-one, molecular formula is , belongs to benzoxazole compound.

The ability of two-component dyeing photoinitiating systems for the radical polymerization of 1,6-hexanediol diacrylate (HDDA) and 2-ethyl-2-(hydroxymethyl)-1,3-propanediol triacrylate (TMPTA) is presented. The systems under study comprised a hemicyanine dye as a sensitizer and iodonium salts that played a role of a coinitiator. The kinetic parameters of the polymerization reaction, such as the rate of polymerization (R-p) and the degree of conversion of monomer (C-%), were estimated. The thermodynamic feasibility of an electron transfer process in the systems studied was verified and calculated using the Rehm-Weller equation. It was found that a benzoxazole derivative in the presence of iodonium salts effectively initiated the polymerization of acrylate monomers. The polymerization rates of about 10(-7) s(-1) and the degree of conversion of acrylate groups from 20% to 50% were observed. The effects of photoinitiator structures on the initiating ability and spectroscopic properties of sensitizers are described in this article.
