    摘要: Process for controlling the breaking of an oil-in-water emulsion using an organic emulsion breaker comprising the steps of:A. adding the organic emulsion breaker to the emulsion by slow intermittent or continuous addition to produce a broken water phase;B. continuously passing a beam of light through the broken water phase;C. continuing the slow addition of the organic emulsion breaker to the broken water phase;D. continuously or intermittently measuring both the unadsorbed light passing through the broken water phase and the light scattered forward by oil droplets in the broken water phase;E. determining from the measurements in step D, the turbidity of the broken water phase; andF. discontinuing the addition of organic breaker when the turbidity reaches a first minimum value following a maximum value.

    摘要: A process for the prevention of the growth of microorganisms, especially in industrial water, comprises contacting these microorganisms with an effective antimicrobial amount of a reaction product of .epsilon.-caprolactam and an N-alkylalkylene diamine with the reaction being carried out in the liquid phase for 3 to 20 hours at a temperature about 180.degree.C. The process further comprises incorporating into said industrial water an effective amount of a sequestering agent comprising a water-soluble phosphonic acid which forms a complex with a divalent metal, a water-soluble salt of the acid and the mixtures thereof, with the weight ratio of sequestering agent to reaction product being 1:10 to 10:1.

    摘要: Aqueous media having a dissolved content of a small amount, (less than 100 p.p.m.) of a mixture of aminoalkanols of the formula: ##STR1## wherein R.sub.1 and R.sub.2 each represent H and C.sub.1-18 unbranched alkyl substituents (the sum of the carbon atoms in R.sub.1 and R.sub.2 being 9 to 18), R.sub.3 and R.sub.4 each represent H,C.sub.1-4 alkyl and C.sub.2-4 hydroxyalkyl substituents, x represents 2 to 6, and y represents 0 to 1, the ##STR2## units in the aminoalkanols being of at least two different chain lengths in the range of 11 to 20 carbon atoms, possess decreased tendency to corrode iron-containing metals including steel. The mixtures are also useful in salt form. The efficiency of the mixture is improved by various additives which act synergistically therewith.
