甲基苯駢三氮唑

簡稱TTA,分子式為 C7H7N3 ,易吸濕,主要是金屬(如銀、銅、鉛、鎳、鋅等)的防鏽劑和緩蝕劑

外觀性狀


白色顆粒或粉末,可加工成大片狀、小片顆粒狀、柱狀、精細顆料狀、粉狀

基本用途


本品主要用作金屬(如銀、銅、鉛、鎳、鋅等)的防鏽劑和緩蝕劑,廣泛用於防鏽油(脂)類產品中,多用於銅及銅合金氣相緩蝕劑潤滑油添加劑、循環水處理劑、汽車防凍液。本品也可與多種阻垢劑、殺菌滅藻劑配合使用,尤其對封閉循環冷卻水系統緩蝕效果甚佳。

基本特性


純品系白色顆粒或粉末,是4-甲基苯駢三氮唑與5-甲基苯駢三氮唑的混合物,熔點80-86℃,難溶於水,溶於醇、苯、甲苯、氯仿等有機溶劑,可溶於稀鹼液。

生產工藝


①在反應釜中,將3,4二氨基甲苯置於純水中,加熱溶解;
②向步驟①所成的溶液中加入3,4二氨基甲苯的亞硝酸鈉,進行反應;
③將步驟②所成溶液冷卻;
④在步驟③所成溶液中滴入硫酸,出現大量結晶體生成;
⑤將步驟④所得混合物進行脫液處理;
⑥將步驟⑤所得結晶體加熱,脫水
⑦將步驟⑥所得結晶體進行蒸餾,製成所述的5-甲基苯駢三氮唑;本發明的生產方法以3,4二氨基甲苯為原料,通過中壓合成、酸化、脫水、蒸餾處理,製備5-甲基苯駢三氮唑的工藝簡單、製備過程容易控制,收率高、純度高,生產成本低、易於組織工業化生產。

Molecular formula: C7H7N3 Molecular Weight: 133.16
Specification:
itemsindex
AppearanceWhite or Light yellow particle shape solid
Active contentwt %99.0 min
Melting point ℃80-86
Ash content %0.1 max
Water content %0.2 max
Properties:
TTA can be used as corrosion inhibitor of copper and copper alloy, it also has corrosion inhibition for black metals. This product is absorbed on metal surface to form a thin membrane to protect copper and other metals from corrosion of air and other harmful subjects. The membrane is more uniform. When used together with MBT, the effect is better.
Usage:
First, dissolved with alcohol or alkali, then added into circulating water system, the dosage of 2-10mg/L is preferred. If the metal is badly corroded, 5-10 times of normal dosage should be expected.
Package and Storage:
25kg inner liner polyethylene (PE) bag, outer plastic woven bag,, or confirmed by clients. Storage in room shady and dry place.
