Chemical Name: Ortho -Toluenediamine (O-TDA& OTD)
Normalized Isomer ration: 3, 4-Toluenediamine: CAS: 496-72-0 60% 2, 3-Toluenediamine: CAS: 2687-25-4 40% Molecular formula: C7H10N2 Properties: It is light gyey solid and very unstable at normal temperature so that its color can change quickly. ================================= Quality index: Inspection Item Appearance light gyey solid Purity (%) ¡Ý99.8 Melting point(degree)60 -62 Moisture(%) ¡Ü0.20 Density(24degree) 1.05 pH scope 11.5-12.0 ================================= Uses: It is used as chemical intermediate in order to corrosion inhibitor tolyltriazole, antioxidant MMB etc. 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. It can substitute for o-phenylenediamine, and can be used many other fields such as epoxy resin curing, inimer formed, cross-linked of polymer. Packing: 204kgs/balck drum |
