시마진 C화학적 특성, 용도, 생산
화학적 성질
Simazine is a combustible, white crystalline solid. Practically odorless.Its solubility in methanol is 400mg/L, its solubility in water is 5mg/L, its solubility in petroleum ether is 2mg/L and it is slightly soluble in chloroform. It has the advantages of stable chemical property, but it is easily hydrolyzed under the strong acid or alkali conditions and at higher temperatures to produce inactive hydroxyl derivatives. No corrosion. Original medicine m.p.224℃.
용도
Simazine is a preemergence herbicide used to control
broadleaf and grassy weeds. It is also used as a soil sterilant.
Principal crops involved include maize, citrus, and deciduous
fruit. Simazine is also used in aquatic weed control.
생산 방법
Simazine is prepared by reacting two equivalents of ethylamine
in the presence of an acid acceptor. It is stable in neutral
and slightly basic or acidic media, but is hydrolyzed by
stronger acids and bases especially at higher temperatures.
Primary exposures occur during application, not during
production, and include both inhalation and dermal components.
정의
ChEBI: A diamino-1,3,5-triazine that is N,N'-diethyl-1,3,5-triazine-2,4-diamine substituted by a chloro group at position 6.
일반 설명
White to off-white crystalline powder.
공기와 물의 반응
Insoluble in water.
반응 프로필
Simazine is hydrolyzed by strong acids and alkalis .
건강위험
Inconsistent data in the literature; oral LD50values in rats reported as 970 and 5000 mg/L,showing a wide difference; toxicity is of loworder.
화재위험
Literature sources indicate that Simazine is nonflammable.
농업용
Pre-emergence herbicide, Algaecide: and ornamental crops, turf grass, orchards, and vineyards. At higher rates, it is used for non-selective weed control in industrial areas. Before 1992, simazine was used to control submerged weeds and algae in large aquariums, farm ponds, fish hatcheries, swimming pools, ornamental ponds, and cooling towers. Simazine is available in wettable powder, waterdispersible granule, liquid, and granular formulations. It may be soil-applied. Not approved for use in EU countries. A U.S. EPA restricted Use Pesticide (RUP) for all land uses because of its potential to contaminate ground water

잠재적 노출
A potential danger to those involved in the manufacture, formulation, and application of this preemergence herbicide. Pesticide not in use; TRI and/or IUR indicates importers or manufacturers are unlikely. Banned for use in the EU.
Carcinogenicity
No tumorigenic response was
seen in mice treated orally at doses ranging from 75 to
215mg/kg. In a 2-year feeding study in rats, 100 ppm
produced mammary tumors. Sarcomas at the injection
sitewere produced in another study ofboth rats and mice.
Simazinewas fedtoratsatdoselevelsequivalent to 0,0.5,5,and
50mg/kg for 2 years.Bodyweight and hematological changes
were seen primarily at the highest dose. After 24 months at
50mg/kg, an increase in ovarian atrophy and Sertoli cell
hyperplasia were seen. Increases in mammary gland tumors
were seen in females at 50mg/kg.

비 호환성
Powder may form explosive mixture with air. Incompatible with strong oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, epoxides.
폐기물 처리
Strong acid or alkaline hydrolysis leads to complete degradation of simazine. However,large quantities of simazine should be incinerated in a unit operating @ 850℃ equipped with off-gas scrubbing equipment. In accordance with 40CFR165, follow recommendations for the disposal of pesticides and pesticide containers. Must be disposed properly by following package label directions or by contacting your local or federal environmental control agency, or by contacting your regional EPA office.
