Electrolytic descaling The method of surface preparation which can be used for ballast tanks before drydocking It bases on a breakdown of the rust using very strong electrical current The current is produced by galvanic reaction between steel and large amount of magnesium anodes fitted for this purpose in the ballast tank which is completely filled with seawater (electrolyte)

Alkanes from Reduction of Carboxylates - Kolbe's Electrolytic method Last updated Save as PDF Page ID 66938 Contributors Sodium or potassium salt of a dicarboxylic acid on electrolysis gives an alkene An alkene is generated when an aqueous solution of sodium or potassium salt of a dibasic acid (with adjacent carboyxlic groups) is electrolyzed

This method is applicable for the preparation of symmetrical alkanes only and not suitable for the preparation of methane In Kolbe's electrolytic methods the alkane obtained is always a higher alkane due to the formation of carbon-carbon (C―C) bond restricting the formation of methane by this process Properties of Alkanes Physical

The Kolbe electrolysis or Kolbe reaction is an organic reaction named after Hermann Kolbe The Kolbe reaction is formally a decarboxylative dimerisation of two carboxylic acids (or carboxylate ions) The overall reaction is: If a mixture of two different carboxylates are used all combinations of them are generally seen as the organic product structures:

use of electrolytic suppression in the recycle mode Whereas AN 175 and AU 161 describe methods to measure chloride and existent sulfate in ethanol AN 290 demonstrates a method to measure both existent and potential sulfate and chloride in ethanol 5 In the AN 290 method a Dionex IonPac AS4A-SC column is used for separation after direct injection of the ethanol samples and a Dionex AMMS 300
