Abstract
The composition of reaction mixtures, particularly in the production of ammonium sulphate, is controlled by an apparatus responsive to differences in conductivity or temperature between a standard reaction mixture and a sample from the process when a neutralizing agent is added to each. The standard mixture and the sample are brought to the same temperature before the neutralizing solution is added. Specification 772,866, [Group XXXV], is referred to.
