N,N-ДИМЕТИЛЦИКЛОГЕКСИЛАМИН химические свойства, назначение, производство
Химические свойства
CLEAR LIQUID
Использование
Dimethylcyclohexylamine is used
in polyurethane plastics and textiles and as a chemical
intermediate.
Методы производства
N,N-Dimethylcyclohexylamine is manufactured either by the reaction of methyl
chloride or formaldehyde and hydrogen with cyclohexylamine (HSDB 1989).
Определение
ChEBI: A tertiary amine consisting of cyclohexane having a dimethylamino substituent.
прикладной
The curing temperature of baking finishes comprising polyurethane-forming substances can be reduced by 50 – 80 ℃ by adding weakly acidic derivatives of N,N-Dimethylcyclohexylamine. Like pyridine, dimethylcyclohexylamine catalyzes certain reactions and is slightly more efficient than pyridine in the preparation of acid chlorides with thionyl chloride. It can be used as corrosion inhibitor and as an antioxidant in fuel oils.
Общее описание
Colorless liquid with a musky ammonia odor. Less dense than water.
Реакции воздуха и воды
Highly flammable. Water soluble.
Профиль реактивности
N,N-Dimethylcyclohexylamine neutralizes acids in exothermic reactions to form salts plus water. May be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. Flammable gaseous hydrogen may be generated in combination with strong reducing agents, such as hydrides.
Угроза здоровью
Inhalation of high concentration of vapor will will produce irritation of the respiratory tract and lungs. Inhalation of large quantities of vapor may be fatal.
Пожароопасность
Behavior in Fire: Dangerous when exposed to heat or flame. Can react vigorously with oxidizing materials.
Промышленное использование
This amine is used as a catalyst in the production of polyurethane foams. It is also
used as an intermediate for rubber accelerators and dyes and in the treatment of
textiles.
Профиль безопасности
Poison by ingestion.
Moderately toxic by inhalation. Whenheated to decomposition it emits toxic
fumes of NOx
Метаболизм
There is no record of any metabolic studies with MTV-dime thy ley clohexylamine.
However, one can predict that it would be oxidized to the N-oxide by either a
cytochrome P-450 system (Damani 1982) or the flavin-containing monooxygenase
(Ziegler 1988). Mixed function oxidase enzymes would be expected to produce
demethylation (Lindeke and Cho 1982). Many studies describe the metabolism of
the parent compound cyclohexylamine (Henderson 1990).
