2,4-D’s Uses

  • 2,4-D is used and sold in many different forms in a wide variety of brand-name products and is used in over 1,500 herbicide products. 2,4-D is most commonly used for:

  • Weed control in lawns and other turf

  • No-till burndown

  • Control of weeds and brush along fences and highway and railroad rights of way

  • Conifer release (control of broad-leaf trees in conifer plantings)

  • Grass hayfields and pastures

  • Cereal grains

  • Corn and sorghum (occasionally)

  • As a synthetic auxin analogue

How it s made
How It’s Made

2,4-D is commonly prepared by the condensation of 2,4-dichlorophenol with monochloroacetic acid in a strongly alkaline medium at moderate temperatures (Canada, NRC, 1978; Sittig 1980; QueHee & Sutherland, 1981), or by the chlorination of phenoxyacetic acid, but this method leads to a product with a high content of 2,4-dichlorophenol and other impurities (Melnikov, l97l). Higher reaction temperatures and alkaline conditions during the manufacture of 2,4-D increase the formation of polychlorinated dibenzo- p-dioxin (CDD) by-products (Fig. 2). The alkali metal salts of 2,4-D are produced by the reaction of 2,4-D with the appropriate metal base.

How It’s Made Cont’d

Amine salts are obtained by reacting stoichiometric quantities of amine and 2,4-D in a compatible solvent (QueHee & Sutherland, 1974, 1981). Esters are formed by acid-catalysedesterification with azeotropic distillation of water (QueHee & Sutherland, 1981) or by a direct synthesis in which the appropriate ester of monochloroacetic acid is reacted with dichlorophenol to form the 2,4-D ester (Canada, NRC, 1978).

Examples of organic molecule projects


2,4-D was developed during World War II by a British team, aiming to increase crop yields for a nation at war. When it was commercially released in1946, it became the first successful selective herbicide and allowed for greatly enhanced weed control in wheat, maize (corn), rice, and similar cereal grass crops, because it only kills dicots, leaving behind monocots. 2,4-D is the third most commonly used herbicide in North America and the most widely used herbicide in the world.

What are the uses for ascorbic acid

Ascorbic acid is an essential nutrient in human diets, and necessary to maintain connective tissue and bone. Its biologically active form, vitamin C, functions as a reducing agent and coenzyme in several metabolic pathways.

Ascorbic acid is easily oxidized and is used as a reductant in photographic developer solutions (among others) and as a preservative.

A vitamin used in preventing scurvy, as a strong reducing agent and as an antioxidant.

Ascorbic acid is added to many foods for its nutritive value, but is also used to prevent flavors and colors from being damaged by oxidation. It is often used in canned or frozen fruits to prevent the browning that accompanies oxidation.

Ascorbic acid prevents damage from oxygen free radicals.

Other uses: Assists delayed wound and bone healing, chronic disease (Asthma, Pre-eclampsia, Age-related Macular Degeneration, Osteoarthritis, Cancer, the Common Cold, High Blood Pressure, Heart Disease) and urine acidification.

HOW IS ASCORBIC ACID MADE? necessary to maintain connective tissue and bone. Its biologically active form, vitamin C, functions as a reducing agent and coenzyme in several metabolic pathways.

  • Steps 1 thru 9 (Starch Hydrolysis): Corn starch is broken down into simple sugar (D-Glucose) by the action of heat and enzymes. Step 10 (Hydrogenation): D-Glucose is converted into D-Sorbitol. Step 11 (Fermentation): D-Sorbitol is converted into L-Sorbose. Step 12 (Acetonation): L-Sorbose is combined with an acid at low temperatures. Step 13 (Oxidation): The product is then oxidized with a catalyst, acidified, washed and dried forming L-Gluconic Acid. Step 14 (Hydrolysis): L-Gluconic Acid is treated with hydrochloric acid forming crude ascorbic acid. Step 15 (Recrystallization): The crude ascorbic acid is filtered, purified and milled into a fine crystalline powder.

How it s made1
How it’s Made Nomenclature

The demand for vanilla flavoring has long exceeded the supply of vanilla beans. Because of this, vanillin now can be made through chemical synthesis. Vanillin was first synthesized from eugenol. Later it was synthesized from lignin-containing "brown liquor", a byproduct of the sulfite process for making wood pulp, but the lignin process is no longer popular because of environmental concerns. Today most vanillin is produced from the petrochemical raw material guaiacol. Several routes exist for synthesizing vanillin from guaiacol. At present, the most significant of these is the two-step process in which guaiacol reacts with glyoxylic acid by electrophilic aromatic substitution. The resulting vanilmandelic acid is then converted to vanillin by oxidative decarboxylation. In October 2007, Mayu Yamamoto of the International Medical Center of Japan developed a way to extract vanillin from cow dung.

  • The Chemical Way

How it s made2
How it’s Made Nomenclature

Natural vanillin is extracted from the seed pods of Vanilla planifola. As harvested, the green seed pods contain vanillin in the form of its β-D-glycoside. The green pods do not have the flavor or odor of vanilla. After being harvested, their flavor is developed by a months-long curing process.
