PROCESS FOR THE PREPARATION OF LITHIUM CHROMATE

Inventia se refera la un procedeu de obtinere a cromatului de litiu, destinat utilizarii ca inhibitor de coroziune pentru protectia otelului nealiat în sisteme apoase de bromura de litiu, folosite ca agent termic în pompele de caldura. Inventia realizeaza un cromat de litiu dihidrat cu o compozitie...

description	Inventia se refera la un procedeu de obtinere a cromatului de litiu, destinat utilizarii ca inhibitor de coroziune pentru protectia otelului nealiat în sisteme apoase de bromura de litiu, folosite ca agent termic în pompele de caldura. Inventia realizeaza un cromat de litiu dihidrat cu o compozitie chimica medie de 98,2% Li2CrO4.2H2O, folosind ca materie prima anhidrida cromica, hidroxid de litiu monohidrat si solutie de hipoclorit de sodiu cu un randament de 94...95%. Filtratul este supus cristalizarii prin evaporare la (50...40)+/- la presiune atmosferica sau în vid (300...400) mmHg, dupa care cristalele sînt uscate la maximum 105 degree C.
