Pentanedione, also known as acetylace tone, is an intermediate of the fungicides methyl pyrimethanil, pyrimethanil and the herbicide methyl sulfonon.
Used as pharmaceutical raw materials and organic intermediates, but also as a solvent
Used as analytical reagent and extraction agent for aluminum in tungsten and molybdenum
Acetylace tone is an organic synthesis intermediate, which can form amino-4, 6-dimethylpyrimidine with guanidine, and is an important pharmaceutical raw material.It can be used as solvent of cellulose acetate, additive of gaso line and lubricant, desiccant of paint and varnish, fungicide, insecticide and so on.Acetylace tone also Chemicalbook can be used as petroleum cracking, hydrogenation reaction and carbonylation reaction catalyst, oxygen oxidation accelerator.It can be used to remove metal oxides in porous solids and to treat polypropylene catalyst.In Europe and the United States more than 50% used in livestock antidiarrheal drugs and feed additives.
In addition to the typical properties of alcohols and ketones, it has a dark red color with ferric chloride and forms chelates with many metal salts.It is prepared by condensation of acetic anh ydride or acetyl chlor ide with ace tone, or by reaction of ace tone with ketene.Chemicalbook is used as metal extractant to separate trivalent and tetravalent ions, paint and ink desiccant, pesticides, fungicides, solvents for high polymers, reagents for determination of thallium, iron, fluor ine and intermediates for organic synthesis, etc.
Transition metal chelating agent.Determination of iron and fluor ine by colorimetric method and thallium in the presence of carbon disulfide.
Fe(III) complexometric titration indicator;For the modification of guanidine groups (e.g., Arg) and amino groups in proteins
Used as a transition metal chelator;Used for colorimetric determination of iron, fluor ine and thallium in the presence of carbon disulfide
An indicator for iron (III) complexometric titration.Used to modify guanidine groups in proteins and amino groups in proteins.
