  • Patent number: 8785696
    Abstract: The present invention provides a phosphorus compound of formula (I). The phosphorus compound is prepared by reacting a compound of formula (II) with alkylene carbonate. As compared with the conventional phosphorus compounds as flame-resistant additives, the phosphorus compound of the present invention has not only a high pyrolysis temperature but also excellent solubility in most of the organic solvents with high or low polarity, and is therefore a suitable flame-resistant additive for use in thermosetting or thermoplastic resins.

  • Patent number: 7964750
    Abstract: A method for synthesizing 9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide or its derivatives has a step of introducing 6-chloro-6H-dibenz[c,e][1,2]oxaphosphorin or its derivative, an acid compound and water into a reacting chamber to form an organic layer having 9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide or its derivative and an aqueous layer. Because the acid compound is from an external source and has a catalyzing effect, employing the method can prevent side reaction from occurring and increase yield of 9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide or its derivative. Furthermore, the method is a one-pot operation of hydrolysis, dehydration and cyclization, so the method does not require purification of intermediates. Therefore, the method is time- and cost-saving and requires less organic solvent, resulting in less pollution to the environment.
