在以甲基丙烯基磺酸钠为第三单体,硫氨酸钠为溶剂的腈纶一步法生产中,由于疏氰酸钠中的甲酸钠有较强的链转移作用,其含量超过某值时,致使浆液粘度大大下降而影响正常生产,因此测定硫氰酸钠中甲酸钠的含量是十分必要的。 用中和法生产的氰化钠和硫黄合成的硫氰酸钠产品(含二分子结晶水)中,甲酸钠含量通
In the one-step production of acrylic with sodium methacylsulfonate as the third monomer and sodium methionine as solvent, sodium formate in sodium cyanate has a strong chain transfer effect. When the content exceeds a certain value , Resulting in a significant decline in the viscosity of the slurry affect the normal production, so the determination of sodium thiocyanate sodium content is very necessary. Sodium cyanide produced by the neutralization method and sulfur products of sodium thiocyanate (containing two molecules of crystal water), sodium content through
