Reaction of 2-amino-5-R-phenyl-!,3,4-thiadizoles with unsaturated acids and acid chlorides in the presence of trimethylamine takes place exclusively at the amino group to form the 2-carboxyalkyl-and 2-acylamino-derivatives, respectively. 2-Amino-l,3,4-thiadiazoles, including their acyl derivatives,
## Abstract In this paper the corrosion behaviour of copper in 5% (by weight) citric, sulphuric and hydrochloric acids is studied. The efficiency of 2βaminoβ5βmercaptoβ1,3,4βthiadiazole (AMT) as a corrosion inhibitor is compared with the use of benzotriazole (BTA). The experimental techniques were
This paper studies the use of 5% (wt) citric acid without inhibitor, inhibited with benzotriazole (BTA) and 2-amino-5-mercapto-1,3,4thiadiazole (AMT) and de-aerated with nitrogen in the cleaning of 18th and 19th century chalcographic plates. DC and AC electrochemical techniques have been used to cha
