Dacthal Chemical Properties,Uses,Production

Chemical Properties

Colorless crystalline

Chemical Properties

Colorless to gray crystalline solid. Practically odorless.


Pre-emergent herbicide.


Selective, nonsystemic, preemergent herbicide to control most annual grasses and many broad-leaved weeds.

Potential Exposure

DCPA is an alkyl phthalate; benzene- dicarboxylic acid herbicide, pesticide pre-emergent herbi- cide is used on annual broadleaf weeds and grasses in a wide spectrum of vegetable crops.

First aid

Eyes: Speed in removing material from skin is of extreme importance. Eye contact can cause dangerous amounts of these chemicals to be quickly absorbed through the mucous membrane into the bloodstream. Directly, irrigate with large amounts of plain, tepid water or saline for 20 minutes, occasionally lifting the lower and upper lids. During this time, remove contact lenses, if easily removable without additional trauma to the eye. Get medi- cal aid immediately. Have physician check for possible delayed damage. Skin: Get medical aid. Skin and/or eye contact can cause dangerous amounts of these chemicals to be absorbed into the bloodstream. Wearing the appropriate PPE equipment and respirator for organochlorine pesti- cides, immediately flush exposed skin, hair, and under nails with plain, running, tepid water for 20 minutes, then wash twice with mild soap. Shampoo hair promptly if contami- nated; protect eyes. Do not scrub skin or hair, since this can increase absorption through the skin. Rinse thoroughly with water. Victims who are able and cooperative may assist with their own decontamination. Remove and double-bag contaminated clothing and personal belongings. Leather absorbs many organochlorines; therefore, items such as leather shoes, gloves, and belts should be discarded. If the skin is swollen or inflamed, cool affected areas with cold compresses. Ingestion: Call poison control. Loosen all clothing. Never give anything by mouth to an unconscious person. Get medical aid. Do not induce vomiting. In cases of ingestion, the patient is at risk of CNS depression or seizures, which may lead to pulmonary aspiration during vomiting. If the victim is conscious and able to swallow, administer an aqueous slurry of activated charcoal at 1 gm/kg (usual adult dose 60 90 g, child dose 25 50 g). A soda can and straw may be of assistance when offering charcoal to a child. The efficacy of activated charcoal for some organochlorine poisoning (such as chlordane) is uncertain. If victim is unconscious or having convulsions, do nothing except keep victim warm. In some cases you may be specifically instructed by Poison Control to induce vomiting by way of two tablespoons of syrup of ipecac (adult) washed down with a cup of water. Do not give acti- vated charcoal before or with ipecac syrup. Inhalation: Get medical aid. Do not contaminate yourself. Wearing the appropriate PPE equipment and respirator for organochlo- rine pesticides, immediately remove the victim from the contaminated area to fresh air. For inhalation exposures, monitor for respiratory distress. If the victim is not breath- ing, administer artificial respiration. Do not use mouth-to- mouth method if victim ingested or inhaled the substance; give artificial respiration with the aid of a pocket mask equipped with a one-way valve or other proper respiratory medical device. If cough or breathing difficulty develops, evaluate for respiratory tract irritation, bronchitis, or pneumonitis. If breathing is difficult, administer 100% humid- ified supplemental oxygen through bag/mask apparatus until medical help arrives. Do not leave victim unattended

Environmental Fate

Soil. Bartha and Pramer (1967) reported that DCPA was degraded by soil microorganisms via cleavage of the herbicide molecule into propionic acid and 3,4-dichloroaniline. The acid was mineralized to carbon dioxide and water and two molecules of 3,4-dichloroaniline were condensed to form 3,3′4,4′-tetrachloro-azobenzene. Metabolites identified in soil and turfgrass thatch are monomethyl tetrachloroterephthalate and 2,3,5,6-tetrachloroterephthalic acid (Hartley and Kidd, 1987; Krause and Niemczyk, 1990). Residual activity in soil and the half-life in soil were reported to be approximately 3 months (Hartley and Kidd, 1987; Worthing and Hance, 1991)


UN3077 Environmentally hazardous substances, solid, n.o.s., Hazard class: 9; Labels: 9-Miscellaneous hazardous material, Technical Name Required.


May react violently with strong oxidi- zers, bromine, 90% hydrogen peroxide, phosphorus trichloride, silver powders or dust. Incompatible with silver compounds. Mixture with some silver compounds forms explosive salts of silver oxalate.

Waste Disposal

Incineration in a unit with efficient gas scrubbing. Containers must be disposed of properly by following package label directions or by con- tacting your local or federal environmental control agency, or by contacting your regional EPA office.
