메트올카르브 C화학적 특성, 용도, 생산
개요
Metolcarb (17), m-tolyl methylcarbamate
(IUPAC), C9H11NO2, MW 165.2, mp 76–77 ?C, is a colorless
solid that is moderately soluble in water and is readily
soluble in polar organic solvents.
화학적 성질
Metolcarb is a colorless crystalline
solid.
용도
Metolcarb is used to control planthoppers, leafhoppers and other
sucking pests on rice. It is also used for control of citrus mealybugs, onion
thrips, Mediterranean fruit flies, pink bollworms and cotton aphids.
제조 방법
Metolcarb is produced by the reaction between 3-
methylphenol and Metolcarb.
일반 설명
Colorless crystalline solid. METOLCARB is an insecticide for the control of rice leafhoppers, planthoppers, codling moth, citrus mealybug, onion thrips, fruit flies, bollworms and aphids. Not registered as a pesticide in the U.S.
공기와 물의 반응
Soluble in water.
반응 프로필
METOLCARB is a carbamate ester. Carbamates are chemically similar to, but more reactive than amides. Like amides they form polymers such as polyurethane resins. Carbamates are incompatible with strong acids and bases, and especially incompatible with strong reducing agents such as hydrides. Flammable gaseous hydrogen is produced by the combination of active metals or nitrides with carbamates. Strongly oxidizing acids, peroxides, and hydroperoxides are incompatible with carbamates.
건강위험
High oral and skin toxicity, and moderate inhalation toxicity. (Non-Specific -- Carbamates) Some carbamates appear to be carcinogenic, teratogenic, and/or mutagenic. Carbamates are cholinesterase inhibitors.
화재위험
As for other solid carbamate pesticides, container may explode in heat of fire. Fire and runoff from fire control water may produce irritating or poisonous gases. Emits toxic fumes of nitrogen oxides when heated to decomposition. Avoid decomposing heat.

moth; citrus mealy bug; onion thrips; fruit flies; bollworms
and aphids. Not registered as a pesticide in the United
States.
신진 대사 경로
The main pathways of metabolism of metolcarb in plants, mammals and
insects involve ring-methyl, N-methyl and phenyl-ring hydroxylation
and conjugation. Carbamate ester hydrolysis is a minor reaction. Further
oxidation of a ring-hydroxymethyl moiety to carboxyl occurs in rats and
insects.

비 호환성
Carbamates are incompatible with reducing
agents such as hydrides, strong acids, oxidizing acids,
peroxides, and bases. Contact with active metals or nitrides
cause the release of flammable, and potentially explosive,
hydrogen gas. May react violently with bromine, ketones.
Incompatible with azo dyes, caustics, ammonia, amines,
boranes, hydrazines, strong oxidizers.
폐기물 처리
Consult with environmental
regulatory agencies for guidance on acceptable disposal
practices. Generators of waste containing this contaminant
(≥100 kg/mo) must conform to EPA regulations
governing storage, transportation, treatment, and waste
disposal. 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.
