Hexamethylene diisocyanate (HDI) is the organic compound with the formula (CH 2) 6 (NCO) 2. It is classified as an diisocyanate. It is a colorless liquid. [2] It has sometimes been called HMDI [3] but this not usually done to avoid confusion with Hydrogenated MDI.

Hexamethylene diisocyanate is a pale yellow liquid with a strong odor. It is an industrial chemical that is not known to occur naturally. It is also commonly known as HDI, 1,6-hexamethylene diisocyanate, 1,6-diisocyanatohexane, Mondur HX, and Desmodur H. Hexamethylene diisocyanate is mainly used to make polyurethane foams and coatings. It is ...

以HDI 、HDI缩二脲或三聚体为原料生产的聚氨酯涂料，具有不泛黄、耐候性强等特点，广泛用于航空、汽车、建筑、木器、塑料、皮革等方面。 该产品也用作干性醇酸树脂交联剂和合成纤维的原料. 用于生产脂肪族类聚氨酯涂料，也可作干性醇酸树脂交联剂和皮革涂饰剂。 1.己二胺与二氧化碳或盐酸反应生成己二胺碳酸盐或盐酸盐，再经光化反应，然后经蒸馏除去溶液，经精馏得HDI。 HDI与水和催化剂反应合成HDI缩二脲，然后经薄膜蒸发器蒸发，脱除残余HDI，加入溶纤剂配 …

六甲撑二异氰酸酯，也被称为HDI（Hexamethylene diisocyanate），是一种重要的有机化合物，常用于聚氨酯的制备。 以下是六甲撑二异氰酸酯的制备方法： 1.

2025年1月27日 · Hexamethylene diisocyanate is an aliphatic diisocyanate monomer typically used to produce oligomers and prepolymers that when combined with a polyol produce light-stable polyurethane. Highly reactive 1,6-hexamethylene diisocyanate (HMDI) was used to synthesize lactic acid polymers from oligomers by the addition of 2,2′-bis(2-oxazoline) (BOX ...
