zelf-alkaliserend Explanation: is dit misschien een optie?..is wel niet exact "zelf loog aanmakend"...maar ik denk dat dit bedoeld wordt -------------------------------------------------- Note added at 2 hrs (2012-06-13 17:26:03 GMT) -------------------------------------------------- in navolging van je in de discussie gemaakte opmerking: zelf-verloging of zelf-verlogen? -------------------------------------------------- Note added at 2 hrs (2012-06-13 17:26:55 GMT) -------------------------------------------------- dat wil zeggen de automatische vorming van het overeenstemmende loog |

Reference Reference information: misschien is het goed om bij 'causticizing' te beginnen (chemical engineering) A process for converting an alkaline carbonate into lime. Read more: http://www.answers.com/topic/causticization#ixzz1xgsXQ9ki Chemical recovery and causticizing process Chemical recovery is an important part of the kraft process: recovering chemicals from the spent cooking liquor, reconstituting them to form fresh cooking liquor, producing energy from the incineration of organic residuals and minimizing air and water pollution (fig. 1). Figure 1. Principle of causticizing Causticizing plays an important role in the chemical balance of a kraft mill, because this process regenerates cooking liquor. The object of the causticizing process is to turn inactive sodium carbonate (Na2CO3) into the active cooking chemical, sodium hydroxide, and of course to make sure that the conversion efficiency of carbonate into hydroxide is as high as possible. The process can be divided into three parts: slaking, causticizing and white liquor clarification/filtration, http://www.tappsa.co.za/archive3/Journal_papers/Advanced_con... -------------------------------------------------- Note added at 2 hrs (2012-06-13 17:33:53 GMT) -------------------------------------------------- Natriumhydroxide (caustische soda, bijtende soda of bekend onder de handelsnaam Destop), formule NaOH, is een witte, hygroscopische stof met een smeltpunt van 319 °C en een dichtheid van 2,13 g/cm³. De stof lost onder grote warmteontwikkeling in water op tot natronloog. Opgelost in water is het een sterke base en verdringt zwakkere basen uit hun zouten. http://nl.wikipedia.org/wiki/Natriumhydroxide Sodium hydroxide, also known as lye and caustic soda,[2][3] with the molecular formula NaOH is a caustic metallic base which is a white solid available in pellets, flakes, granules, and as a 50% saturated solution. It is soluble in water, ethanol and methanol. This alkali is deliquescent and readily absorbs moisture and carbon dioxide in air. Sodium hydroxide is used in many industries, mostly as a strong chemical base in the manufacture of pulp and paper, textiles, drinking water, soaps and detergents and as a drain cleaner. Worldwide production in 2004 was approximately 60 million tonnes, while demand was 51 million tonnes.[4] Although molten sodium hydroxide also possesses similar properties, the high temperature required limits applications. http://en.wikipedia.org/wiki/Sodium_hydroxide |
