新的色酚AS衍生物的合成及对C.I.颜料红57∶1的改性研究

Syhthesis of novel derivatives of Naphtol AS and modification used for C.I. Pigment Red 57∶1

对含有极性基团 (—COOH,— SO3 H)的色酚 AS衍生物的合成及其反应的影响因素进行了研究 ;合成了 4种新的色酚 AS苯环 3或 4上含有— COOH或— SO3 H基团的衍生物 ;利用该类衍生物作为第二偶合组分 ,采用混合偶合工艺对颜料红 57∶ 1进行改性研究 ,研究了其添加量对改性颜料的着色力、色光。

The synthesis of derivatives of Naphtol AS containing polar groups(_COOH,_SO 3H)and factors affecting the reaction have been studied.Four derivatives of Naphtol AS containing _COOH or _SO 3H groups in the 3 or 4 position of the phenyl ring were synthesized.Derivatives of Naphtol AS as the second coupling component were used in mixed coupling and the effect of its added amount on the colour strength,hue,flowability and dispersing extent(in water)of pigments was studied.
