Hydrazine organic coatings crosslinking agent
2017-3-17 11:24:00
Hydrazine organic coatings crosslinking agent,Organic hydrazide and dicyandiamide, is also a kind of high melting point solid, but the crosslinking temperature is lower than dicyandiamide.
Organic hydrazide and epoxy resin composition system of one-component epoxy resin adhesive storage period can be up to more than 4 months, the commonly used organic hydrazide compounds are: succinic acid hydrazide and adipic acid hydrazide, sebacic acid hydrazide, isophthalic acid hydrazide and p-hydroxy benzoic acid hydrazide (POBH), etc.
Different kinds of organic hydrazide crosslinking temperature is not the same, because the crosslinking temperature is higher, reason often join the accelerator to reduce the crosslinking temperature, the promoter and dicyandiamide basic same.
Hydrazine is a kind of structure of the general formula for RCONHNHRl or RSO2NHNHRl compounds, which are collectively referred to as hydrazide, the latter for sulfonyl hydrazine (sulfonyl hydrazide).
Type, R for fat hydroxyl or aromatics base, R1 for hydrogen, fat hydrocarbon, aromatic hydrocarbon, acyl, etc.
Such as acetyl hydrazine CH3CONHNH2, benzene sulfonyl hydrazine C6H5SO2NHNH2, N, N '- diacetyl hydrazine CH3CONHNHCOCH3, etc.
Usually with carboxylic acid, carboxylic acid ester and acyl halide, anhydride, sulfonyl bittern reaction with hydrazine or hydroxyl replace hydrazine production respectively.
Used as a reagent in organic synthesis, and some used drugs (such as isoniazid).
Carboxylic acid and its derivatives with reaction generated or hydroxyl replace hydrazine compounds known as hydrazide containing R1CONHNHR2 groups.
Adipic acid hydrazide aka and hydrazide, single product is white crystal, soluble in water, poisoning. Mainly used in epoxy powder coating curing agent and coating additives, metal attenuated agent and other polymer additives and water treatment agent. With bifunctional crosslinking reagent, dedicated to aldehyde, generated a relatively stable hydrazone links. With sodium hyaluronate as protein drug carrier after crosslinking. And diacetone acrylamide in water emulsion and water soluble polymer crosslinked crosslinking role. Can also be used for indoor formaldehyde adsorbent materials and intermediates.
Adipic acid hydrazide English name: Hexanedioic acid, dihydrazide; Adipic dihydrazide; Adipic acid dihydrazide; Adipodihydrazide; Adipoyl Hydrazide. Hexanedioic acid dihydrazide
Mainly used in epoxy powder coating curing agent and coating additives, metal attenuated agent and other polymer additives and water treatment agent.
Adipic acid hydrazide double functional group compounds, with sodium hyaluronate as protein drug carrier after crosslinking. And diacetone acrylamide in water emulsion and water soluble polymer crosslinked after crosslinking role, such as coating, adhesive, fiber and plastic processing, hair gel, etc., also can be used as a curing agent and coating epoxy powder coating additives, metal attenuated agent and other polymer additives and water treatment agent, indoor formaldehyde adsorbent materials and intermediates.
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
With bifunctional crosslinking reagent, dedicated to aldehyde, generated a relatively stable hydrazone links. Especially for connecting glycoprotein, such as antibodies.
Isophthalic formyl hydrazine is a chemical formula is C8H10N4O2.
Isophthalic formyl hydrazine English alias: Isophthalohydrazide; M - phthaloyl dihydrazide; 1, 3 - denzenedi carboxylic acid dihydrazide; 1, 3 - Benzenedicarboxylic acid dihydrazide
P-hydroxy benzoic acid hydrazide formula: C7H6O3 colorless to white crystal prisms. Poisonous. Stimulating, should be kept sealed away from light. P-hydroxy benzoic acid is widely used in organic synthesis of raw material. Also widely used in food, cosmetics, medicine, anti-corrosion, fungicide and fungicide, etc.
There are many types of the production method of hydroxy benzoic acid, phenol potassium carboxylation method is suitable for industrialized production, the method and points of phenol potassium solid-phase carboxylation, potassium phenol solvent carboxylation, phenol continuous gas liquid phase method of potassium and carbon dioxide.
P-hydroxy benzoic acid potassium 2 also can be obtained by salicylic acid potassium transposition. So industry can also be by salicylic acid through into salt, inversion, and get p-hydroxy benzoic acid, but the cost is higher. In addition, when producing saccharin byproduct of p-toluene sulfonyl chloride, via ammonification, oxidation and acid, alkali fusion and acid evolution analysis also can receive the goods.
