TogliattiAzot (Russian: ТольяттиАзот) is a Russian chemical company, sometimes described as the world's largest ammonia producer.[1][2] It is headquartered in Tolyatti, Russia.
The main ammonia plant in Tolyatti was constructed as a joint project of the Soviet government and Armand Hammer and started operation in 1979.[3] The company's subsidiary Transammiak operates the Tolyatti-Odessa ammonia pipeline, the longest ammonia pipeline in the world. A marine ammonia terminal is under construction at Port Taman near Taman, Russia.[4]
The company's president is Vladimir Makhlai, who "acquired a big chunk of it when it was privatized in 1992".[1] In the mid-2000s the company was "hit by legal challenges and criminal probes"[5] supposedly instigated by Viktor Vekselberg in an attempt to take over the ownership.[6]
