为提高有机颜料在水中的分散性(D.E.),研究了颜料P.R.254、P.R.255和P.V.19在紫外光照射下的表面改性。经紫外光照射后,颜料在水中的D.E.均得到明显提高,即使经过长时间静置(如24h),其D.E.仍比未处理的样品高。对于P.R.255,D.E.可提高74...为提高有机颜料在水中的分散性(D.E.),研究了颜料P.R.254、P.R.255和P.V.19在紫外光照射下的表面改性。经紫外光照射后,颜料在水中的D.E.均得到明显提高,即使经过长时间静置(如24h),其D.E.仍比未处理的样品高。对于P.R.255,D.E.可提高74.0%;对于P.R.254,D.E.可提高67 4%;对于P.V.19,D E 可提高100.0%。在相同光强度下,对于P.R.255和P.V.19,照射时间越长,颜料的D.E.越好;对于P.R.254,照射时间延长,D.E.下降,但仍比未处理样品高。光强度对颜料D.E.的影响无规律性。还比较了处理后颜料的色光、透明度、墨色及流动性。展开更多

The crystal structure was determined by X-ray diffraction method and the chemical formula weight of the complex is 336.44. The crystal structure of the title complex belongs to orthorhombic space group Pbca and cell parameter s: a=0.853 31(12) nm, b=0.820 42(12) nm, c=3.989 4(6) nm. V=2.792 8(7) nm3, Z=8, Dc=1.600 g·cm-3, The compound is an one-dimension chain complex of infinite length which are connected with hydrogen bond and bri dging coordination water.
