性质描述: | 红色粉状,微溶于热水、乙醇和丙酮。在浓硫酸中为红光紫色,稀释时呈微红紫色,再转为红棕色沉淀;在硝酸中为棕红色溶液,在烧碱液中不变,稍微溶解。其醇溶液遇盐酸呈棕光紫色。着色力高,耐晒、耐酸及耐热性一般,遮盖力差。 |
生产方法: | 由吐氏酸(2-萘胺-1-磺酸)重氮盐与2-萘酚偶合,经松香、烧碱进行松脂化后,用氯化钡完成色淀化,再经后处理,即得产品。1.重氮化2.偶合3.色淀化产品要求色光与标准品近似,得色力为标准品100±5(分),水分含量≤4.5%,水溶性盐含量≤3.5%,吸油量50±5%,耐热性130℃,耐晒性4级,耐酸性及耐碱性均为3级,水渗性及油渗性均为2级,细度(痛过60目筛余物含量)≤5%。原料消耗(kg/t)吐氏酸(100%) 3802-萘酚(100%) 235亚硝酸钠(工业) 120盐酸(31%) 445烧碱(100%) 145松香(特级) 130氯化钡(工业) 480 |
用途: | 主要用于油墨、水彩、油彩、蜡笔等的着色,也可用于油漆。 |
