APPLICATIONS

Sulfoxide (R2SO) is any of various organic sulfur compounds having the group -SO (sulfinyl group) whereas sulfone (RSOOR) with the group -SO2 (sulfonyl group). They are derived from oxidation of sulfides. The common examples of sulfone compounds are dapsone (4,4'-sulfonylbisbenzenamine) and its derivative. Dapsone (4,4'-sulfonylbisbenzenamine) is a parent compound in preparing sulfonamide antibacterial agents such as acedapsone, acetosulfone, glucosulfone, sulfoxone and solapsone. Dapsone and its derivatives have bacteriostatic activity against a broad spectrum of gram-negative and gram-positive organisms. Dapsone is a primary treatment for Dermatitis herpetiformis and in the treatment of leprosy (Mycobacterium leprae infections) leads to apparent improvementas. It is used in the prophylaxis of falciparum malaria. It is a white crystalline powder; melting point 175 - 180C; insoluble in water and vegetable oils. Dapsone is also widely used in polymer industry as a cross linkage agent in manufacturing polysulfone amide engineering plastics. Sulfone-containing engineering plastics are thermally stable and have high resistance property to acids and alkalis. Tazobactam is a penicillanic acid sulfone derivative which acts as a beta-lactamase inhibitor similar to sulbactam. Tazobactam is used in combination with piperacillin to widen the spectrum of activity. Sulfone class compounds which have a sulfonyl group attached to two carbon atoms are active as an antibiotic.

Organosulfone compounds are widely used in refineries, steamcrackers, aromatic extraction and petrochemical manufacturing as they acts as;

  • Hydrotreating catalysts
  • Initial catalyst improvers
  • Sulfur sources
  • Catalyst presulfiding
  • Natural gas sulfur recovery

Organosulfone compounds are also used in;

  • Organic synthesis as organosulfur sources into target organic molecules for the manufacture of pharmaceuticals, adhesives biocides and agricultural products.
  • Polymer production
  • Lubricant and fuel additives for extreme pressure functionality
  • Extraction and reaction solvent
  • Metal treatment
  • Fungicide

Allyl- is the prefix for the univalent organic group, -CH2=CHCH2. Allyl alcohol is an example, CH2=CHCH2OH, clear, pungent liquid, boiling at 96 C; soluble in water. It is prepared from allyl chloride by hydrolysis. Allyl compound, an alkene hydrocarbon, has a vinyl group, CH2=CH-, attached to a methylene -CH2. Because of the highly reactive solid bond, allyl can undergo free radical addition to solid bond which readily combine with themselves or other monomers to form homopolymers or co-polymers which are used in the production of coatings, adhesives and elastomers. In addition to free radical addition, allyl compounds can participate in a wide variety of reactions including electrophilic additions, allylic substitution and oxidation.  Allyl, an unsaturated bond, imparts a characteristic odor in some compounds. An example is allyl isothiocyanate which is the main ingredient of black mustards. (white mustard consists principally of p-hydroxybenzyl isothiocyanate). Allyl isothiocyanate is called mustard oil. Allyl esters are involved in fragrance, flavor, or odor. Allyl Phenyl Sulfone is used for the synthesis of 1-alkyl-2-methylethenes and for Michael additions to enones. It is used in the production of unsaturated nitriles.
