Abstract

The invention belongs to the technical field of polyether polyol and particularly relates to a preparation method of straw oil polyether polyol. The preparation method of straw oil polyether polyol comprises the following steps: neutralizing straw oil with an epoxy compound or alcohol; adding a base catalyst; and finally, adding the epoxy compound for a polymerization reaction to generate straw oil polyether polyol. According to the preparation method provided by the invention, the problems of easy acid corrosion, easy caking and easy coking in burning of the straw oil are solved, and the application field of the straw oil is widened. The straw oil polyether polyol prepared from the straw oil can be applied to the fields such as methanol gasoline additives, biodiesel, fuels, polyurethane additives, cutting grinding aids and lubricants.

Description

technical field [0001] The invention belongs to the technical field of polyether polyols, and in particular relates to a preparation method of straw oil polyether polyols. Background technique [0002] Biomass thermal cracking refers to the process in which biomass is thermally degraded in the absence of oxygen or anoxic conditions, and finally generates bio-oil, charcoal and combustible gas. Bio-oil produced by biomass thermal cracking and liquefaction can be further separated to extract fuel oil and chemical raw materials. Bio-oil contains complex organic components. These organic substances are mainly organic substances with large molecular weight. So far, the analysis of bio-oil components is still under discussion. researching. [0003] Straw oil belongs to biomass energy, which comes from crop straw or wood waste in nature. [0004] In "Analysis and Emulsification of Bio-Oil from Pyrolysis of Corn Stalk Powder", Wang Lihong et al. analyzed the components of bio-oil p...
