Non-toxic grade coating crosslinking agent,Non-toxic grade coating cross-linking agent, polyamine, formaldehyde and phenol is nice nice addition reaction of man by man multivariate amine, non-toxic level of crosslinking agent application security, and under the low temperature crosslinking bisphenol A type epoxy resin, can be in 80% humidity and underwater applications, crosslinking little shrinkage.
Polyamine is a class of compounds containing two or more amino, raw materials for its synthesis of ornithine, key enzymes are ornithine decarboxylase. The most common and have important physiological function of polyamine is putrescine, cadaverine, and spermine, and spermine. Polyamine has a role in promoting growth of some organizations, for the normal maintenance of membrane also plays an important role. Mechanism is not very clear about them.
They are of positive charge amino make them with the negatively charged phosphate group and combined with DNA and RNA, promoting plant cells and animal cells of the transcription of DNA and RNA translation; They can be combined with membrane proteins or phospholipids, keep the film its stability.
Polyamine (DAM) to contain 4, 4 '- diamino diphenyl methane (MDA), 2, 4' - MDA, 2, 2 '- a mixture of MDA and phenyl methane polyamine, under normal temperature for light yellow solid, dissolve in most organic solvents and hydrochloric acid, insoluble in gasoline, n-hexane and water. DAM is a kind of important chemical intermediates, mainly used for the preparation of MDI series products, can also be used for the curing agent of epoxy resin, polyester resin structured agent, etc., instead of the more expensive triethanolamine ester titanate.
Formaldehyde, chemical formula experiment or CH? O, type of 30.03, also known as formaldehyde. Have a special stimulating odour, colorless gas, can irritate the eye, nose, etc. Gas relative density 1.067 (= 1) air, liquid density of 0.815 g/cm3 (20 ℃). - 92 ℃, melting point, boiling point 19.5 ℃. Soluble in water and ethanol. The concentration of the aqueous solution of up to 55%, usually 40%, called formalin, commonly known as formalin (formalin), is a colorless liquid with pungent odor.
Formaldehyde has strong reducing effect, especially in alkaline solution. Burns, vapor and air form explosive mixture, explosion limit of 7% - 7% (volume). Ignition temperature about 300 ℃.
Formaldehyde by methanol under the silver, copper and other metal catalytic dehydrogenation or oxidation, the hydrocarbon oxidation product separated. Used for pesticide and disinfectant, phenolic resin, urea formaldehyde resin, whalen, methenamine, season of amyl alcohol and four dyes such as raw materials.
Chinese name: Diethyl toluene diamine(DETDA)
Chinese alias: aryl, aryl diethyl - aryl - methyl-p-phenylenediamine
English name: Benzenediamine, ar, ar-diethyl-ar-methyl-English aliases:Diethyltoluenediamine; ar, ar-Diethyl-ar-methylbenzenediamine;Diethylmethylbenzenediamine;
CAS No. :68479-98-1
EINECS No. :270 -877-4
Molecular formula: C11H18N2
Molecular Weight: 178.28
Boiling point: 310 ℃
Refractive index: 1.581
Flash Point: > 140 ℃
Inchi: InChI = 1/C11H18N2/c1-4-8-6-7 (3) 10 (12) 11 (13) 9 (8) 5-2/h6H ,4-5,12-13H2 ,1-3H3 density : 1.022
Risk Codes: R10; R35
RIDADR: UN 3082
Safety instructions: S2; S26; S39; S61
Packing Group: III
Hazard Class: 6.1
Industrial formaldehyde solution containing 37% and 15% methanol, formaldehyde as inhibitor, the boiling point of 101 ℃.
Phenol, Phenol, C6H5OH) is a kind of special odor colorless needle crystal, toxic, the production of certain resin, disinfectant, preservative and important raw material of drugs (eg, aspirin). Can also be used for disinfection of surgical instruments and waste processing, skin disinfection, itching, and otitis media. 43 ℃, melting point temperature slightly soluble in water, soluble in organic solvents. When the temperature higher than 65 ℃, can with water in any proportion miscibility. Phenol corrosive, after contact will make local protein denaturation, its available alcohol washing solution to stick to the skin. A small number of phenol is exposed to the air oxidation by oxygen for quinone are pink. In the ferric iron ion turned purple, often use this method to test of phenol.
Phenol molecules made up of a hydroxy directly on the benzene ring. Due to the stability of the benzene ring, this structure is almost not into ketone type structure.
Such as YouShangTu phenol resonance structure. Phenolic hydroxyl oxygen atoms with sp2 hybridization, provide a pair of unpaired electron and benzene ring of six carbon atoms together to form the domain key. Big PI strengthens enol acid, hydroxy push electronic effect and strengthened the polarity of O - H keys, so in the phenol hydroxyl hydrogen can be ionized.
Can be due to the benzene ring structure, the use of phenol on the ring similar benzene electrophilic substitution reaction, such as nitrification and halogenated: the corresponding reaction of benzene and comparison, phenol replace much easier than the benzene ring. This is because the hydroxyl to electronic effect, increase the density of electron cloud of benzene ring.
It is worth noting that electrophilic substitution of phenol happen when hydroxyl ortho and counterpoint. This is for electronic groups such as hydroxyl in common.
