싸이오다이캅(티오디캅) C화학적 특성, 용도, 생산
개요
Thiodicarb, 3,7,9,13-tetramethyl-5,11-
dioxa-2,8,14-trithia-4,7,9,12-tetra-azapentadeca-3,12-di
ene-6,10-dione (IUPAC), consists of colorless crystals, which
are sparingly soluble in water, readily soluble in
dichloromethane, acetone, methanol, and xylene.
Thiodicarb is produced by reaction of N,N -thiobis(methylcarbamic
acid fluoride) with 2-methylthioacetaldoxim in the presence of a base.
용도
Thiodicarb is used as an insecticide.
일반 설명
Colorless to pale tan crystals. Non corrosive. Used as an insecticide.
공기와 물의 반응
Hydrolyzed by strong acid or base.
반응 프로필
A carbamate derivative. 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.
농업용
Insecticide, Molluscicide, Ovicide: Not approved for use in EU countries. Registered
for use in the U.S. Thiodicarb is used primarily on cotton,
sweet corn, and soybeans. The remaining usage is spread
among leafy vegetables, cole crops, ornamentals, and
other minor use sites. Thiodicarb acts as an ovicide against
cotton bollworms and budworms.

환경귀착
Soil. Under aerobic and anaerobic soil conditions, thiodicarb degrades to methomyl
and methomyl oxime (Hartley and Kidd, 1987). The reported half-life in various soils is
3–8 days (Hartley and Kidd, 1987).
신진 대사 경로
The initial metabolic reaction of thiodicarb in soils, plants and animals
is the hydrolytic or thiolytic cleavage of the N-S bond to methomyl.
The subsequent metabolic pathway of methomyl involves hydrolysis /
elimination reactions to yield S-methyl-N-hydroxythioacetimidate and
ultimately acetonitrile and CO
2 as the major terminal products. The metabolic
pathways of thiodicarb are presented in Scheme l. See also the
methomyl entry.
