Application

(1) It is used as chemical intermediate in order to corrosion inhibitor tolyltriazole, antioxidant MMB etc.

(2) OTD as a polyether initiator made the polyether, The foam being made of this polyether have uniformity , meticulous properties, and no contraction. It can improve the foam's performance of heat insulation and it's the measurement of low-temperature performance. Besides, polyether which is made of OTD have better compatibility with cyclopentane.

(3) It can substitute for o-phenylenediamine,and can be used many other fields such as epoxy resin curing, inimer formed, cross-linked of polymer.
