2017-4-2 11:38:20
Room temperature latent type coating crosslinking agent, reaction process in SAP (such as the production of anhydrous AlCl3) removed water. The reaction to generate ketone imide direction, end get red brown viscous liquid reaction. Product must be sealed preservation, prevent moisture from entering the. Latent type, the crosslinking agent belongs to the normal temperature water dissociation for multiple primary amine and the corresponding ketones.
Crosslinking agent with GY and 105-05 l amine two, its quality indicators: appearance: yellow transparent viscous liquid. Viscosity 0.5 ~ lPa, s. amine values (mgKOH/g) : 600-800-4. With the reaction of carbonyl compounds (ketone imide) commonly used amine such as ethylenediamine, divinyl three amine, etc., such as methyl ethyl ketone ketone, acetone, butanone, methyl isobutyl ketone, etc.
Condensation reaction of amine itself. A typical example to ask benzene polycondensation reaction of dimethylamine. Between benzene dimethylamine exist in catalyst under 180 ~ 200 ℃ under the condition of condensation reaction, the release of NH3 by sulfuric acid absorption. Reaction of 5 ~ 10 h filter to remove catalyst product amine reduction.
Ethylenediamine, colorless or yellowish oily liquid or water, there are similar to the smell of ammonia. In strong alkaline. (n26D) 1.4540. Flammable. Low toxicity, median lethal dose (rats, through the mouth) 1460 mg/kg. Corrosive.
Divinyl three amine has hygroscopic transparent yellow viscous liquid, stimulating ammonia smell, flammable, in strong alkali. Soluble in water, acetone, benzene, ethanol, methanol, hardly soluble in n-heptane, for copper and its alloy corrosive. Melting point - 35 ℃, boiling point 207 ℃, relative density 0.9586 (20, 20 ℃), the refractive index of 1.4810. Flash point is 94 ℃. This product is the reaction of secondary amine, easy to react with a variety of compounds, its derivatives have a wide range of USES. Easy to absorb moisture and carbon dioxide in the air.
Divinyl three amine main use: use the credential that catalyzes the complexing indicator, gas purifying agent, epoxy resin crosslinking agent, film for textile, also used in synthetic rubber. Active hydrogen equivalent to 20.6. Every 100 standard resin with 8 to 11.
Chinese name: Diethyl toluene diamine(DETDA)
Physical and chemical properties: light yellow transparent liquid, slightly soluble in water, soluble in alcohols, ethers, ketones and other polar organic solvents, and polyether, polyester polyol compatibility.

Divinyl three amine crosslinking: 25 ℃ for 3 hours + 200 ℃ for 1 hour clock or 25 ℃ for 24 hours. Performance: the applicable period of 50 grams of 25 ℃ for 45 minutes, thermal deformation temperature of 95-124 ℃, the bending strength of 1000-1160 kg/cm2, the compressive strength of 1120 kg/cm2, the tensile strength of 780 kg/cm2, elongation is 5.5%, the impact strength 0.4 ft - pounds/rockwell hardness of 99-108. Dielectric constant (50 hz, 23 ℃), power factor 4.1 (50 hz, 23 ℃) 0.009 volume resistance 2 x1016 Ω - cm normal temperature crosslinking, toxicity, heat quantity, suitable period is short.
Methyl ethyl ketone is colorless transparent liquid. Similar acetone smell. Volatile. With ethanol, ethyl ether, benzene, chloroform, oil miscibility. The water soluble in 4, but lower solubility at higher temperatures. 11.3% can form azeotrope with water (water), azeotropic temperature 73.4 ℃ (including butanone 88.7%). Relative density (d204) 0.805. Freezing point - 86 ℃. Boiling point 79.6 ℃. Refractive index (n15D) 1.3814.
Butanone with carbonyl and lively with carbonyl adjacent hydrogen, so prone to all kinds of reaction. Condensation heat, with hydrochloric acid and sodium hydroxide to generate 3, 4 - dimethyl - 3 - hexene - ketone of 2 - or 3 - methyl - 3 - heptene - 5 - ketone. When the sunlight for a long time, produce ethane, acetic acid, condensation products, etc. Diacetyl is generated by the nitric acid oxidation. When using a strong oxidant such as chromic acid oxidation produce acetic acid.
Butanone to heat stable, above 500 ℃ hot tear formation ketene or methyl ketene. With aliphatic or aromatic aldehyde condensation occurs, generate high molecular weight of ketone, cyclic compound, ketal and resin, etc. With formaldehyde in the presence of sodium hydroxide condensation, for example, the first generation 2 - methyl - 1 - butanol - 3 - ketone, then generate methyl isopropenyl ketone dehydration. The compound resin was synthesized from sunlight or ultraviolet light irradiation.
With phenol condensation generated. 2, 2 - (4 - hydroxy phenyl) butane. Reaction with aliphatic esters in the presence of alkaline catalyst, generates beta 2. In the presence of acidic catalyst with anhydride acylation reaction, generate the beta 2. Generate cyanohydrin reaction with hydrogen cyanide. React with ammonia to generate a keto piperidine derivatives. Butanone alpha hydrogen atom replaced by halogen easily generate various halogenated ketone, such as chlorine and chlorine to generate 3-2 - butanone. With 2, 4 - dinitrobenzene hydrazine effect generated yellow 2, 4 - dinitrobenzene hydrazone (m.p. 115 ℃).
