헥사메틸렌디아민 C화학적 특성, 용도, 생산
화학적 성질
Hexamethylenediamine(HMDA) is a strong organic base, e.g., a 10 % aqueous solution has a pH of 12.3 (20°C), and forms stable salts with both organic and inorganic acids. The most important salt is that produced by neutralization with adipic acid (salt strike): the so-called nylon salt or AH salt. This compound is the raw material for the preparation of nylon by thermal dehydration under vacuum.물리적 성질
Hexamethylenediamine is a colorless solid with a typical fishlike amine odor. It is very soluble in water, soluble in alcohols and aromatic solvents, and poorly soluble in aliphatic hydrocarbons.용도
Hexamethylenediamine is mainly used as a monomer to make nylon 6-6. Its derivative hexamethylene diisocyanate (HDI) is used in the production of polyurethane. It acts as a cross-linking agent in epoxy resins. Other applications include fiber, plastics, polyurethane coatings, lubricants, water treatment products and specialty chemicals (biocides, petroleum additives, and phenol purification).주요 응용
Hexamethylenediamine (1,6-hexanediamine, HDA ) may be used in the preparation of the following:polyamides and their hydrolytic and fungal degradability was investigated
mullite ceramics
methoxycarbonylation of 1,6-hexanediamine with dimethyl carbonate to form dimethylhexane-1,6-dicarbamate.
Formation of high polymers, e.g., nylon 66.
dialkyl hexamethylene-1,6-dicarbamate (AHDC), via trans-esterification reaction of HDA and alkyl carbamates (AC) using FeCl3 as catalyst.
1,6-hexanediamine modified magnetic chitosan microspheres for fast and efficient removal of toxic hexavalent chromium.
정의
ChEBI: Hexamethylenediamine is a C6 alkane-alpha,omega-diamine. It has a role as a human xenobiotic metabolite. It derives from a hydride of a hexane.제조 방법
Virtually all hexamethylenediamine is now produced by the catalytic hydrogenation of adiponitrile[111-69-3] :NC(CH2)4CN + 4H2 → H2N(CH2)6NH2.
화학 반응
Other reactions of hexamethylenediamine are typical of aliphatic amines (→ Amines, Aliphatic). The preparation of hexamethylene diisocyanate [822-06-0] by reaction with phosgene is industrially important:H2N(CH2)6NH2+ 2COCl2 → OCN(CH2)6NCO + 4 HCl
The reaction takes place in a chlorinated aromatic solvent with a yield of 95% or more. Hexamethylene diisocyanate can also be produced by converting hexamethylenediamine to an aliphatic urethane, followed by thermal cleavage (→ Isocyanates, Organic).
일반 설명
Hexamethylenediamine, solution appears as a clear colorless liquid. Burns although some effort is required to ignite. Soluble in water. Corrosive to metals and tissue. Produces toxic oxides of nitrogen during combustion. Used to make nylon.공기와 물의 반응
Water soluble.반응 프로필
HEXAMETHYLENEDIAMINE is hygroscopic. Can react with strong oxidizing materials. Incompatible with acids, acid chlorides and acid anhydrides. Also incompatible with ketones, aldehydes, nitrates, phenols, isocyanates, monomers and chlorinated compounds .건강위험
TOXIC; inhalation, ingestion or skin contact with material may cause severe injury or death. Contact with molten substance may cause severe burns to skin and eyes. Avoid any skin contact. Effects of contact or inhalation may be delayed. Fire may produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may be corrosive and/or toxic and cause pollution.화재위험
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.색상 색인 번호
Hexamethylenediamine is used with adipic acid in the synthesis of polyamide plastics.잠재적 노출
HMDA is used as a textile intermedi ate; a raw material for nylon fiber and plastics; in wet strength resins; in the manufacture of oil-modified and moisture-area types of urethane coatings; in the manufac ture of polyamides for printing inks, dimer acids, and tex tiles; and as an oil and lubricant additive (probably as a corrosion inhibitor); as boiler feed water additives; also used in paints and as a curing agent for epoxy resins; mak ing adhesives.운송 방법
