Qingdao Wangtai Catalyst Co., Ltd.

We have high temperature coal tar, medium temperature coal tar and low temperature coal tar. Product description coal tar is a kind of black sticky liquid, and getting from carbon which is being destructive distillation through cutting-off air and enhancing thermal, meantime. Through high temperature carbonization can get high temperature coal tar, on the contrary, it can get low temperature coal tar by low temperature carbonization. We provide high temperature coal tar. physichochemical property coal tar has special distinctive odour. Its relative density is 1.171.21 and the open flash point is at 200 c, and slightly dissolvie in water and soluble in organic solvent, such as benzene, alcohol, aether, chloroform, acetone etc.its fume and air can become explosion mixture, meanwhile, if meeting clear fire, high hot that will have a combustion explosion danger, reacting violently with oxidizer. testmethod typical result api gravity at 60 f astm d- 1298 -13.0 -12.0 max density at 20 deg c, kg1 astm d- 1298 1.1930 1.18 min viscosity sus @210f calc. 910.1 950 max kinematic viscosity at 50 deg c cst astm d-445 99.465 100.000 max bmci calc. 179.3 175 min water content vol % astm d-95 1.8 2.5 max flash point deg c astm d-93 79 75 min toluene insolubles % ams 531-4 5.9 8.0 max sulphur wt % astm d-4294 0.48 0.17 max ash content wt % astm d-482 0.028 0.040 max pour point deg c astm d-97 0 15 max naphthalene 10 max phenol 1.5 max conclusion: qualified
