2. Structure of acetic acid

3. Uses of acetic acid The largest single use of acetic acid is in the production of vinyl acetate monomer. The major esters of acetic acid are commonly used as solvents for inks, paints and coatings. Glacial acetic acid is an excellent polar protic solvent, as noted above. Acetic acid injection into the tumor has been used to treat cancer

4. Structure of lactic acid

5. Uses of lactic acid In medicine, lactate is one of the main components of lactated Ringer's solution and Hartmann's solution. In industry, lactic acid fermentation is performed by lactic acid bacteria, which convert simple carbohydrates . Lactic acid is used as a food preservative, curing agent, and flavoring agent.

6. Structure of tartaric acid

7. Uses of tartaric acid Tartaric acid is found in cream of tartar, which is used in cooking candies and frostings for cakes. Ta rtaric acid is also found in baking powder, where it serves as the source of acid that reacts with sodium bicarbonate . Industrial uses for tartaric acid include within the gold and silver plating process, tanning leather and making blue ink for blueprints .

8. Structure of citric acid

9. Uses of citric acid Citric acid is a weak organic acid found in citrus fruits. It is a natural preservative and is also used to add an acidic (sour) taste to foods and soft drinks . Citric acid’s chemical properties as a weak organic acid make it a powerful water softener. Citric acid is a relatively common ingredient used in cosmetics products to balance the pH level according to Cosmetics Database.

10. Structure of succinic acid

11. Uses of succinic acid Succinic acid is a precursor to some polyesters and a component of some alkyd resins . Succinic acid is used primarily as an acidity regulator in the food and beverage industry. It is also available as a flavoring agent, contributing a somewhat sour and astringent component to umami taste. As an excipient in pharmaceutical products, it is also used to control acidity or as a counter ion.

12. Structure of oxalic acid

13. Uses of oxalic acid Oxalic acid is rubbed onto completed marble sculptures to seal the surface and introduce a shine. Oxalic acid is used as a bleach for wood, removing black stains . O xalic acid is also used for the removal of rust . Vaporized oxalic acid, or a 3.2% solution of oxalic acid in sugar syrup, is used by some beekeepers as a miticide against the parasitic varroa mite.

14. Structure of salicylic acid

15. Uses of salicylic acid Salicylic acid causes shedding of the outer layer of skin. Salicylic acid topical is used in the treatment of acne, dandruff, seborrhea, or psoriasis, and to remove corns, calluses, and warts. Salicylic acid is used in the production of other pharmaceuticals, including 4-aminosalicylic acid, sandulpiride . Salicylic acid is used as a food preservative, a bactericidal and an antiseptic.

16. Structure of benzoic acid

17. Uses of benzoic acid Benzoic acid is mainly consumed in the production of phenol by oxidative decarboxylation . Benzoic acid is a constituent of Whitfield's ointment which is used for the treatment of fungal skin diseases such as tinea, ringworm. In teaching laboratories, benzoic acid is a common standard for calibrating a bomb calorimeter. Benzoic acid was used as an expectorant, analgesic.

18. Structure of benzyl benzoate

19. Uses of benzyl benzoate Benzyl benzoate is an effective and inexpensive topical treatment for human scabies. Benzyl benzoate is used as a repellent for chiggers, ticks, and mosquitoes . It is also used as a dye carrier, solvent for cellulose derivatives, and fixative in the perfume industry.

20. Structure of Dimethyl phthalate

21. Uses of dimethyl phthalate Dimethyl phthalate is used as an insect repellent for mosquitoes and flies . It is also an ectoparasiticide and has many other uses, including in solid rocket propellants, and plastics. Industry Uses
a) Finishing agents
b) Intermediates
c) Plasticizers
d) Processing aids, specific to petroleum production

22. Structure of methyl salicylate

23. Uses of methyl salicylate This product is used to treat minor aches and pains of the muscles/joints . It is used in high concentrations as a rubefacient and analgesic in deep heating liniments. It is used as a bait for attracting male orchid bees for study, which apparently gather the chemical to synthesize pheromones. It is used to clear plant or animal tissue samples of color.

24. Structure of acetyl salicylic acid

25. Uses of acetyl salicylic acid Aspirin is used in the treatment of a number of conditions, including fever, pain, rheumatic fever . Aspirin is used as an anti-inflammatory agent for both acute and long-term inflammation. Aspirin is thought to reduce the overall risk of both getting cancer and dying from cancer. Low-dose aspirin supplementation has moderate benefits when used for prevention of pre-eclampsia.
