1,3-ДИМЕТИЛБУТИЛАЦЕТАТ химические свойства, назначение, производство
Химические свойства
Colorless liquid; mild odor.
Insoluble in water; soluble in alcohol. Combustible.
Использование
Solvent for nitrocellulose and other lacquers.
Подготовка
by direct esterification of Methyl-iso-butylcarbinol with Acetic acid or Acetic
anhydride.
Методы производства
sec-Hexyl acetate is produced via catalytic reaction of 4-
methyl-2-pentanol and acetic acid.
It also occurs naturally in apples and their leaves.
Общее описание
A clear colorless liquid. Flash point 95°F. Less dense than water and insoluble in water. Vapors heavier than air.
Реакции воздуха и воды
Highly flammable. Insoluble in water.
Профиль реактивности
1,3-DIMETHYLBUTYL ACETATE is an ester. Esters react with acids to liberate heat along with alcohols and acids. Strong oxidizing acids may cause a vigorous reaction that is sufficiently exothermic to ignite the reaction products. Heat is also generated by the interaction of esters with caustic solutions. Flammable hydrogen is generated by mixing esters with alkali metals and hydrides. 1,3-DIMETHYLBUTYL ACETATE is incompatible with the following: Nitrates; strong oxidizers, alkalis & acids .
Опасность
Moderate fire risk. Toxic by inhalation.
Угроза здоровью
Headache, dizziness, nausea, irritation to respiratory passages. Irritates eyes.
Пожароопасность
HIGHLY FLAMMABLE: Will be easily ignited by heat, sparks or flames. Vapors may form explosive mixtures with air. Vapors may travel to source of ignition and flash back. Most vapors are heavier than air. They will spread along ground and collect in low or confined areas (sewers, basements, tanks). Vapor explosion hazard indoors, outdoors or in sewers. Runoff to sewer may create fire or explosion hazard. Containers may explode when heated. Many liquids are lighter than water.
Химическая реактивность
Reactivity with Water No reaction; Reactivity with Common Materials: No reaction; Stability During Transport: Stable; Neutralizing Agents for Acids and Caustics: Not pertinent; Polymerization: Not pertinent; Inhibitor of Polymerization: Not pertinent.
Возможный контакт
(n-isomer): Primary irritant (w/o allergic
reaction), (sec-isomer) Human Data. Amyl acetates are
used as industrial solvents and in the manufacturing and
dry-cleaning industry; making artificial fruit-flavoring
agents; cements, coated papers, lacquers; in medications
as an inflammatory agent; pet repellents, insecticides and
miticide. Many other uses.
Экологическая судьба
Chemical/Physical. Slowly hydrolyzes in water forming 4-methyl-2-pentanol and acetic acid.
Перевозки
UN1993 Flammable liquids, n.o.s., Hazard
Class: 3; Labels: 3-Flammable liquid, Technical Name
Required.
Несовместимости
Vapors may form explosive mixture with
air. Incompatible with 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, nitrates. May soften certain plastics.
Утилизация отходов
Dissolve or mix the material
with a combustible solvent and burn in a chemical incinerator
equipped with an afterburner and scrubber. All federal,
state, and local environmental regulations must be observed.
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.
