헥실렌글리콜 C화학적 특성, 용도, 생산
화학적 성질
Hexylene Glycol is an oily colorless liquid with a mild sweet odor. It is an oxygenated solvent derived from acetone which has two alcohol functions. It has a low evaporation rate and it is completely miscible with water.용도
(^+)-2-Methyl-2,4-pentanediol is used to control the flow properties of industrial products such as paints, coatings, cleansers, solvents, and hydraulic fluids. It acts as a thickening agent in cosmetic products. It serves as a coupling agent and an additive to hydraulic fluids, inks and cement. It is also employed as a blood volume expander. Further, it is used as a solvent for cleaning and colorant products. In addition to this, it is used in laboratory studies as a precipitant and cryoprotectant in protein crystallography.생산 방법
2-Methyl-2,4-pentanediol is prepared commercially by the catalytic hydrogenation of diacetone alcohol . It is used as a chemical intermediate, a selective solvent in petroleum refining, a component of hydraulic fluids, a solvent for inks, and as an additive for cement . Industrial exposure is likely to be from direct contact or from inhalation, particularly if the material is heated.정의
ChEBI: A glycol in which the two hydroxy groups are at positions 2 and 4 of 2-methylpentane (isopentane).일반 설명
Oily colorless liquid with a mild sweet odor. Floats and mixes slowly with water.공기와 물의 반응
Hygroscopic. Water soluble [Hawley]반응 프로필
2-Methyl-2,4-pentanediol is incompatible with the following: Strong oxidizers, strong acids [Note: Hygroscopic (i.e., absorbs moisture from the air).] .위험도
Toxic by ingestion and inhalation; irritant to skin, eyes, and mucous membranes. Combustible.건강위험
Irritation of eyes, nose and throat; headache, dizziness, and nausea.화학 반응
Reactivity with Water No reaction; Reactivity with Common Materials: Can catch fire when in contact with porous materials such as wood, asbestos, cloth, soil, or rusty metals; Stability During Transport: Stable at ordinary temperatures, however when heated this material can decompose to nitrogen and ammonia gases. The decomposition is not generally hazardous unless it occurs in confined spaces; Neutralizing Agents for Acids and Caustics: Flush with water and neutralize the resulting solution with calcium hypochlorite; Polymerization: Not pertinent; Inhibitor of Polymerization: Not pertinent.Purification Methods
Dry the diol with Na2SO4, then CaH2 and fractionally distil it under reduced pressure through a packed column, taking precautions to avoid absorption of water. [Beilstein 1 IV 2565.]헥실렌글리콜 준비 용품 및 원자재
