For the first time methylation of quinazolin-4-оne by “soft” and “hard” alkylation agents (methyl iodide, dimethylsulfate, methyltosylate) in proton polar ethanol, aproton аpolar, aproton dipolar solvents (dioxane-1,4, acetonitrile, dimethyl formamide, dimethyl sulfoxide) was studied. It was shown, that the reaction goes in two directions on atom nitrogen N-3 and oxygen O-4. It is find, that N-3/O-4 relation depends on nature of methylation agents, solvent and temperature.

A number of new linearly fused furochromones were synthesized. The methodology was performed starting from naturally occurring visnagin and khellin via enaminone formation using N,N-dimethyl formamide dimethylacetal followed by ring closure in acidic medium. Various reactions on the enaminone derivatives are described.

Comparision between pulping of canola stalks with dimethyl formamide and diethylene glycol was studied in order to investigate the effects of cooking temperature (190˚C, 210˚C, and 230˚C), cooking time (120 min, 150 min, and 180 min) and dimethyl formamide or diethylene glycol (50%, 60%, and 70%) on the properties of pulp and paper. SCAN viscosity was applied to estimate the extent of cellulose degradation. Responses of pulp and handsheet properties to the process were analyzed using statistical software (MINITAB 15). The results showed that DMF pulp of canola was better than DEG pulp of Canol

After modified with octadecyltrichlorosilane (OTS), a superhydrophobic ZnO film was obtained. The superhydrophobic film turned into a superhydrophilic one after UV irradiation, which can be recovered through being placed in the dark.
