  A method for efficiently producing a cyanogen halide with suppressed side effects, and a method for producing a high-purity cyanate ester compound at a high yield includes contacting a halogen molecule with an aqueous solution containing hydrogen cyanide and/or a metal cyanide, so that the hydrogen cyanide and/or the metal cyanide is allowed to react with the halogen molecule in the reaction solution to obtain the cyanogen halide, wherein more than 1 mole of the hydrogen cyanide or the metal cyanide is used based on 1 mole of the halogen molecule, and when an amount of substance of an unreacted hydrogen cyanide or an unreacted metal cyanide is defined as mole (A) and an amount of substance of the generated cyanogen halide is defined as mole (B), the reaction is terminated in a state in which (A):(A)+(B) is between 0.00009:1 and 0.2:1.

  A mineralized collagen matrix with an intrafibrillar and/or extrafibrillar gradient of mineralization for insertion replacement is disclosed. The intrafibrillar mineralization of the collagen matrix is formed by the addition of fetuin to the simulated body fluid. The gradient of intrafibrillar mineralization may stiffen the collagen matrix and simulate a natural insertion for improved cell infiltration and regeneration.

  本发明公开了一种具有矿化胶原基质的矿化胶原基质，其具有纤维内和/或纤维外的矿化梯度，用于插入替换。胶原基质的纤维内矿化是通过向模拟体液中添加胎牛血清蛋白而形成的。纤维内矿化的梯度可能使胶原基质变硬，并模拟自然插入，以改善细胞渗透和再生。
