摘　　要： 己二异氰酸酯(HDI)分子具有特殊的直链饱和结构和含有高度不饱和双键的异氰酸酯基团,化学性质非常活泼,能够与水生成聚二脲,与多元醇反应生成聚胺酯,与胺反应生成缩二脲。在催化剂作用下能生成二聚体和三聚体。HDI及其二聚体和三聚体具有不变黄性,广泛应用于涂料、胶粘剂、皮革等领域。作者主要介绍HDI的主要化学反应的进展。 HDI＇s molecular structure is a special saturated straight chain and it has highly unsaturated double bonds （isocyanate group）. It has such very lively and chemical properties that can be used to form polyurea with water. And it also reacts with polyurethane to form polyol, reacts with amine to biuret. Ontology reactions occur under the catalyst. HDI and its HDI-derivatives own the characteristic of stability, being widely used in coating, adhesive, leather, and other fields. This article reviews the experimental and theoretical studies relating to the chemical reaction of HDI.
