Abstract

The invention relates to tetra-(0,0-dialkyl phosphonyl) p-benzoquinone and a preparation method thereof. The structure of the compound is shown in the specification, wherein R is straight chain or branched chain alkyl containing 1-8 C atoms. The preparation method comprises the following steps: adding a certain molar ratio of chloranil and tris phosphite (P(OR)3) into an organic solvent under the heating condition for carrying out sustained reaction for a period of time, and then, purifying and drying the reactants to prepare the tetra-(0,0-dialkyl phosphonyl) p-benzoquinone. The tetra-(0,0-dialkyl phosphonyl) p-benzoquinone of the invention has high flame resistance, stable physical and chemical properties and good compatibility with high molecular materials, can be used as the flame retardant of polyester, polyamide, epoxy resin, glass reinforced plastic resin, paint and the like, is favorable for environment protection, has simple process, low equipment investment, low cost and high phosphorus content in products, and can realize scale production easily.

Description

Technical field The invention relates to an organic phosphine compound and a preparation method thereof, in particular to a tetra(0,0-dialkylphosphono) p-benzoquinone and a preparation method thereof. The compound can be used as polyester, polyamide, epoxy Flame retardant for resin, FRP resin, paint, etc. Background technique At present, the global demand for halogen-free flame retardants is very high. Because organic phosphine flame retardants have low smoke, low toxicity, and no pollution, they are more popular. The development of environmentally friendly organic phosphine flame retardants has become a flame retardant technology. A research hotspot in the field. Although a new type of organic phosphine flame retardant has been successfully developed, its large-scale production and application have been hindered due to technology, price and processing performance. In addition, due to the large variety of polymer materials, there are also many types of flame retardants that a...
