采用硼酸、乙二醇及1，2，4-丁三醇为原料，一锅法合成了一种含有五元环的硼酸酯键合剂，采用 FTIR、11B NMR、1H NMR和 MS对其结构进行了表征。用在线红外分析手段研究了合成的硼酸酯化合物在常温水中和饱和水蒸气中的水解反应动力学。建立了水解反应动力学模型。结果表明，上述两种条件下硼酸酯水解反应为准一级反应。硼酸酯在常温水中的反应速率常数为2．3×10-5s-1，半衰期约为8．4 h。硼酸酯在饱和水蒸气中的反应速率常数为2．96×10-7s-1，半衰期约为27天。添加0．2％的硼酸酯使 RDX/HTPB炸药的抗拉强度从0．80 MPa提高至1．44 MPa，抗压强度从5．04 MPa提高至13．27 MPa，证明其键合效果良好。

A borate ester bonding agent with a five-membered ring was synthesized via a " one-pot" process using borate acid, ethylene glycol and 1,2,4-butanetriol as raw materials. Its structure was characterized by FTIR,11B NMR,1H NMR and MS. The hydrolysis reaction kinetics of the synthesized borate ester in normal temperature water and in saturated water vapor was investiga-ted by an on-line IR analysis method. The hydrolysis reaction kinetic model was established. The results show that the hydrolysis of the synthesized borate ester under above-mentioned two conditions is the pseudo-first order reaction. The reaction rate constant and half life of the borate ester are 2. 3×10-5 s-1 and 8. 4 h in normal temperature water,2. 96×10-7 s-1 and 27 d in saturated water vapor,respectively. The addition of 0. 2% borate ester makes the tensile strength of RDX/HTPB explosive increase from 0. 80 MPa to 1. 44 MPa and the compressive strength increase from 5. 04 MPa to 13. 27 MPa,proving that the synthesized borate ester has good bonding effect.
