Solubility: slightly soluble in water, soluble in many organic solvents

Uses:

INDUSTRIAL APPLICATION: Butyl acetate is an important organic solvent, widely used in paints, coatings, glues, inks and other industrial fields.

Chemical reaction: it can also be used as a substrate and solvent in organic synthesis for the preparation of other organic compounds.

Preparation method:

Butyl acetate is usually prepared by esterification of acetic acid and butanol, a reaction process that requires the use of an acid catalyst, such as sulfuric acid or phosphoric acid.

Safety Information:

Butyl acetate is an organic solvent and requires the following safety precautions:

Avoid inhalation, skin contact and ingestion; wear protective gloves, glasses and face shield when using.

Use in a well-ventilated area and avoid prolonged exposure to high concentrations.

Store away from ignition sources and oxidizing agents to ensure stability.

In case of accidental contact or inhalation, wash affected area immediately and seek medical help.

Basic information

Main application

Application 1: GB 2760-96 regulations are edible spices allowed to be used. As a spice, a large number of flavors such as bananas, pears, pineapples, apricots, peaches and strawberries, and berries are used. It can also be used as a solvent for natural glue and synthetic resin.

Application 2:  Excellent organic solvents, which are good for the acetate cellulose, ethyl cellulose, chloride rubber, polystyrene, methyl acrylic resin, and many natural resins such as gum, Manila, Dama resin, etc. Soluble performance. It is widely used in nitrifying fiber varnish. It is used as solvents during artificial leather, fabrics and plastic processing, used as extracting agents in various oil processing and pharmaceutical processes, and also used for spice and apricots, bananas, pears, pineapples, etc. Ingredients of various fragrance agents.

Application 3: Used as analytical reagents, chromatography analysis standard substances and solvents.

Emergency treatment

First-aid

Skin contact: Take off the contaminated clothes and rinse the skin with soapy water and water.

Eye contact: Raise the eyelids immediately, rinse with a large amount of water or physiological saline for at least 15 minutes. Medical.

Inhale: Quickly get out of the scene to fresh air. Keep the respiratory tract open. If breathing is difficult, give oxygen. If breathing stops, perform artificial breathing immediately. Medical.

Eater: Drink enough warm water and vomit.

Emergency handling of leakage

Quickly evacuate personnel in the leakage of pollution to the safe area and isolate, and strictly restrict the entry and exit. Cut off the source of the fire. It is recommended that emergency treatment personnel wear self -sufficient positive respirators and anti -static work clothes. Try the leak source as much as possible. Prevent restricted space such as inflowing into the sewer and flood ditch.

Small leakage: absorb with activated carbon or other inertia materials. It can also be rinsed with a lot of water, and the wastewater system is diluted after washing water.

Large leakage: Constructing the embankment or digging a pit. Cover with bubbles to reduce the steam disaster. Use the explosion -proof pump to the slot car or a special collector, recycle or transport it to the waste treatment place for disposal.
