| titleOfInvention | Preparation method for compositing dipentaerythritol with tripentearythritol with high yield coefficient |
| abstract | The invention discloses a preparation method for compositing dipentaerythritol with tripentearythritol with a high yield coefficient. A catalytic agent is activated macromolecule loading solid alkali which is composed of a carrier and active components, wherein the carrier is a macromolecule base body in a styrene copolymerization cross-linked structure, and the active components come from quaternary amine or hydroxy radical combined with the quaternary amine. Highly purified tripentearythritol, crude dipentaerythritol and pentaerythritol are obtained, and purified dipentaerythritol is obtained by refining the crude dipentaerythritol. A yield coefficient of the tripentearythritol is more than 20%, and the content is more than 90%. The dipentaerythritol with a yield coefficient more than 40% is obtained at the same time, and the content is more than 90%. A yield coefficient of pentaerythritol is less than 20%. Few by-product is contained in reaction liquid, and purity is high. The catalytic agent obtained through the preparation method is high in mechanical strength and recyclable, so that the preparation method is environment-friendly and can be carried out on a traditional pentaerythritol production device. The preparation method has a good industrialization prospect. |
