화학적 성질
colourless liquid용도
2-Methyl-m-phenylene Diisocyanate is used in method for preparing breathable sweat-absorbing EVA foam shoe material.정의
ChEBI: A toluene meta-diisocyanate in which the isocyanato groups are at positions 2 and 6 relative to the methyl group on the benzene ring.일반 설명
Liquid. Used in the manufacture of polyurethane foams, elastomers, and coatings; crosslinking agent for nylon 6.반응 프로필
2-METHYL-M-PHENYLENE DIISOCYANATE reacts violently with amines, alcohols, bases and warm water, causing fire and explosion hazards. [Handling Chemcials Safely 1980. p. 907]. Reaction with water to form Carbon Dioxide [Merck 11th ed. 1989].건강위험
Classified as slightly toxic orally. Probable oral lethal dose in humans is 5 to 15 g/kg or between 1 pint and 1 quart for a 70 (l50 lb.) person. Particularly poisonous when breathed. This is among the most poisonous of isocyanates. Acute and chronic exposures to low concentrations may produce asthmatic attacks.화재위험
When heated to decomposition, 2-METHYL-M-PHENYLENE DIISOCYANATE emits toxic fumes of nitrogen oxides. Ventilation should be adequate. If polyurethane products are heated, protection against isocyanate release is necessary. Avoid decomposing heat.Safety Profile
Confirmed carcinogen. Poison by ingestion and inhalation. Human systemic effects by inhalation: olfactory, eye, and pulmonary changes. Flammable liquid. When heated to decomposition it emits toxic fumes of NOx. See also CYANATES.Purification Methods
It is purified by fractional distillation in a vacuum. Store it under N2 in sealed dark ampoules as it is water and light sensitive. Like the preceding 2,4-isomer, it has a sharp pungent odour, is TOXIC and is IRRITATING TO THE EYES. [Beilstein 13 IV 259.]톨루엔-2,6-다이아이소사이안산 준비 용품 및 원자재
