摘要：
The possibility of involving novel resources of renewable oxygen-containing components in the composition of diesel fuel is shown. It is proposed to use paraldehyde and its mixtures with 1,1-diethoxyethane as biofuel components. Renewable bioethanol can be used as a raw material to obtain paraldehyde and its mixtures with 1,1-diethoxyethane. Therefore, this approach can significantly expand the resource base for the production of biodiesel and increase the volume of production and consumption of biodiesel up to 17 %. In the present paper the data on low-temperature properties, viscosity and flash point of diesel fuel samples mixed with 1,1-diethoxyethane and/or paraldehyde are presented and analyzed. 1,1- diethoxyethane has a low pour point and improves low-temperature properties, whereas paraldehyde, on the contrary, worsens them. However, paraldehyde has a more favorable effect on flash point and viscosity than 1,1-diethoxyethane, which significantly reduces them. Thus, by mixing the studied components, it is possible to stabilize the properties of the fuel blend. Diesel blends containing up to 17 % oxygenates meet the requirements of various Classes and can be used as summer fuel, as well as winter and arctic fuel in cold climate regions.
