Naphthenic acid prepared using aluminum sulphate aluminum soap

 Herein, aluminum sulfate prepared using aluminum naphthenate soaps. Naphthenate aluminum soap in the soap is a naphthenic acid . The naphthenic acid soap of calcium naphthenate soaps are not using the sodium and calcium salts of sodium naphthenate ( lime ) for the metathesis reaction from. We are here only for naphthenic acid aluminum soap  aluminum hydroxide simple introduction.
What is the naphthenic acid soaps of aluminum sulfate
Aluminum sulfate naphthenic naphthenic acid soap products are aluminum soap , it was yellow viscoplastic solids . Naphthenic acid sodium soap solution and the aqueous aluminum sulfate solution obtained by the reaction of the product. A mixture of a variety of different molecules , the structure is very complex. Insoluble in water. Thickeners for paints and inhibit penetration. Its character as a yellow semi-solid viscous material . Solution: do not dissolve in water, slightly soluble in ethanol , soluble  titanium dioxide in benzene , toluene, turpentine , etc. It is used as a varnish driers , but also for the preparation of lubricants.
Preparation of aluminum sulphate aluminum soap reason naphthenic
 When aluminum sulfate violently expanding when heated and become a sponge -like material . Thermal decomposition of red burn sulfur trioxide and aluminum oxide. When the relative humidity of about 25% lower weathering . Soluble in water, practically insoluble in ethanol , the solution is acidic. Long after boiling insoluble basic salt precipitation. The Metallic stearate  relative density of 1.62 . Aluminum sulfate is a widely used industrial reagent , usually with alum confusion.
Naphthenate, aluminum sulfate and aluminum soap by double decomposition reaction of sodium soap obtained . And many family members naphthenic acid soap , rich colors. Calcium naphthenate , cobalt naphthenate , lead naphthenate , manganese naphthenate . The cobalt salt is violet blue , lead salt is brown , copper green, amber zinc , manganese salt is brown. They can also be used as pesticides, paint driers and preservatives .
