    • Provided is a process for preparing 10-chloro-9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide (DOPO-C) compound, the process having steps of: reacting a liquid chlorinating agent and 9,10-dihydro-10-hydroxy-9-oxa 10-phosphaphenanthrene 10-oxide compound represented by formula (B) to form a mixture, the mixture comprises DOPO-C compound represented by formula (A) and an unreacted liquid chlorinating agent, separating the DOPO-C compound and the unreacted liquid chlorinating agent from the mixture to obtain the DOPO-C compound; wherein X1, X2, and X3 are each independently selected from the group consisting of hydrogen atom, hydroxyl group, cyano group, sulfonic acid group, sulfonate ester group represented by —SO3R1, halogen atom, alkoxy group represented by —OR2, acyclic hydrocarbon group having 1 to 8 carbon atoms, cyclic alkyl group having 3 to 8 carbon atoms, aryl group, heteroaryl group, and arylalkyl group, wherein R1 and R2 are each an acyclic hydrocarbon group having 1 to 8 carbon atoms.
    • 本发明提供一种制备10-氯-9,10-二氢-9-氧杂-10-磷杂菲-10-氧化物(DOPO-C)化合物的方法,该方法具有以下步骤:使液体氯化剂与9,10- 由式(B)表示的二氢-10-羟基-9-氧杂10-磷杂菲10氧化物化合物以形成混合物,该混合物包含由式(A)表示的DOPO-C化合物和未反应的液体氯化剂,将DOPO -C化合物和未反应的液体氯化剂,得到DOPO-C化合物; 其中X 1,X 2和X 3各自独立地选自氢原子,羟基,氰基,磺酸基,-SO 3 R 1表示的磺酸酯基,卤素原子,-OR 2表示的烷氧基,无环烃基 具有1至8个碳原子,具有3至8个碳原子的环状烷基,芳基,杂芳基和芳基烷基,其中R 1和R 2各自是具有1至8个碳原子的无环烃基。
