Abstract Bitumen contains approximately 5 wt% sulfur so it must be removed before being used as fuel. Herein, we performed oxidative desulfurization of bitumen at room temperature using n-pentane and ultrasound to reduce viscosity mix the bitumen-dissolved aqueous reaction solution physically. The states in ratio were investigated confirm process. Additionally, developed a novel method for sepa...

A protocol for the coupling of potassium xanthogenates with ?-(trifluoromethyl)styrenes in presence triethyl phosphite is reported. The reaction carried out under blue light irradiation organic photocatalyst 3DPAFIPN. proceeds via formation alkyl radicals from readily available xanthogenate salts oxidative desulfurization and cleavage carbon–oxygen bond assisted by phosphite.
