Sodium thiocyanate CAS 540-72-7
Sodium thiocyanate bụ kristal na-enweghị agba nke nwere akụkụ abụọ nke mmiri kristal. Na okpomọkụ 30.4 ℃, ọ na-efunahụ mmiri kristal ya wee ghọọ sodium thiocyanate na-anaghị agbaze, nke a na-agbaze na mmiri na ethanol. A na-emepụta ya site na azeotropic distillation nke sodium cyanide na sulfur slurry n'ụlọ ọrụ mmepụta ihe, ọ bụkwa otu n'ime ngwaahịa nhicha nke gas oven coke na osisi coking. A na-emepụta ya site na mmiri mkpofu nke usoro anthraquinone disulfonic acid.
