Usage

Description

Chemical Properties

faintly yellow liquid

Uses

Different sources of media describe the Uses of 2855-13-2 differently. You can refer to the following data:
1. Isophorone diamine is a common hardener for epoxy resins.
2. One of the three epoxy networks based on diglycidyl ether of bisphenol-A epoxy prepolymer cured with aliphatic amines, namely triethylenetetramine (TETA), 1-(2-aminoethyl) piperazine (AEP) and isophoronediamine (IPD). ?Allergic contact dermatitis (ACD) ca
3. Isophorondiamine mainly used as epoxy curing agents, mainly for applications requiring low color, low odor, high flexural strength and excellent chemical resistance of epoxy formulations. Suitable for floor coatings, fillers and paving mixes.

General Description

A clear to light-yellow liquid. Highly soluble though slightly denser than water. May be toxic by inhalation and skin absorption. Corrosive to skin. Used to make other chemicals.

Air & Water Reactions

Soluble in water. Flash Point 234 F. Melting point 50 F. Reacts with carbon dioxide from the air to form deposits around vents (Roger Patrick, DuPont Engineer).

Reactivity Profile

ISOPHORONE DIAMINE is an amine. Amines are chemical bases. They neutralize acids to form salts. These acid-base reactions are exothermic. The amount of heat that is evolved per mole of amine in a neutralization is largely independent of the strength of the amine as a base. Amines may be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides (Roger Patrick, DuPont Engineer). Corrodes aluminum and steel in the presence of moisture and carbon dioxide [USCG, 1999].

Health Hazard

Inhalation of high concentrations of vapor causes irritation, coughing, and nausea. Eyes: May cause inflammation/burns. Skin: May cause burns. Ingestion: Nausea.

Fire Hazard

Combustible material: may burn but does not ignite readily. When heated, vapors may form explosive mixtures with air: indoors, outdoors and sewers explosion hazards. Contact with metals may evolve flammable hydrogen gas. Containers may explode when heated. Runoff may pollute waterways. Substance may be transported in a molten form.

Contact allergens

Isophorone diamine is widely used in urethane and epoxy coatings for light-stable, weather-resistant prop- erties. It is used in water proofing and paving concret- ing, and in the manufacture of diisocyanates and polyamides as an epoxy resin hardener. It is a strong sensitizer and can cause airborne contact dermatitis.

Method for preparing IPDI (isophorone diisocyanate)

The invention discloses a method for preparing IPDI (isophorone diisocyanate). The method comprises the following steps: (1) isophorone and hydrogen cyanide are subjected to a reaction in the presenceof a catalyst to obtain isophorone nitrile; (2) isophorone nitrile obtained in step (1), ammonia and hydrogen are subjected to a reaction in the presence of a catalyst to obtain isophorone diamine; (3) isophorone diamine is subjected to a phosgenation reaction to obtain IPDI, wherein the content of impurities containing secondary amine groups in isophorone diamine subjected to the phosgenation reaction in step (3) is smaller than or equal to 0.5wt%, preferably smaller than or equal to 0.3wt%, and more preferably smaller than or equal to 0.1wt%. By means of the method, content of hydrolyzed chlorine in the IPDI product can be effectively reduced, the yellowing resistance of the product is effectively improved, and the harm that downstream products are unqualified due to existence of hydrolyzed chlorine in the product is reduced.

Process For Preparing Amino Compounds From Nitrile Compounds

The present invention relates to a process for hydrogenating nitrile compounds to amino compounds, in which the cross-sectional loading of the reactor during the hydrogenation is less than or equal to 4.0 kg/m2*s, based on the liquid phase.
