Abstract: IMPROVED COMPOSITIONS ARE DESCRIBED FOR INHIBITING CORROSION IN SYSTEMS USING WATER AS THE HEAT TRANSFER MEDIUM. THE COMPOSITIONS ARE AQUEOUS DISPERSIONS DISPERSIONS COMPRISING AN ALIPHATIC LONG CHAIN AMINE AND FROM ABOUT 0.20 TO ABOUT 1 PART OF N-PHENYL (HIGHER ALKYL) LOWER ALKYL QUATERNARY DIAMINE PER PART OF THE LONG CHAIN ALIPHATIC AMINE. THE PROCESS OF PREPARING THE DISPERSION AND ITS USE TO INHIBIT CORROSION ARE ALSO DISCLOSED.

Abstract: A material which produces heat when in contact with water is added to a water containing liquid mixture and the increase in temperature is recorded. From a known relationship between water content and temperature increase resulting from contact between water and the material, the water content of the liquid mixture is easily determined.

Abstract translation: 当与水接触时产生热量的材料被加入到含水的液体混合物中并且记录温度的升高。 从水和材料之间的接触引起的水含量和温度升高之间的已知关系，容易确定液体混合物的含水量。
