- A hydrogen donor in the synthesis of methyl furan via catalytic transfer hydrogenation of furfural over a ruthenium/ruthenium oxide/carbon catalyst.
- A reagent in one-pot synthesis of brominated derivatives of 1,3-dioxolane.
- A solvent for the synthesis of organic molecules such as 2, 4-diaminopyrimidines and 4-aza-podophyllotoxins.
| | 製造方法 | By catalytic reduction of methyl n-propyl ketone. | | 定義 | ChEBI: A secondary alcohol that is pentane substituted at position 2 by a hydroxy group. | | 一般的な説明 | 2-Pentanol, a secondary alcohol, is a volatile organic compound (VOC) that is a common aroma-active component of food and beverage products. | | 安全性プロファイル | Moderately toxic by ingestion and intraperitoneal routes. A narcotic. A skin and severe eye irritant. Flammable liquid when exposed to heat or flame; can react with oxidzing materials. A severe explosion hazard when exposed to heat or flame. To fight fire, use alcohol foam, dry chemical. When heated to decomposition it emits acrid smoke and irritating fumes. See also ALCOHOLS | | 職業ばく露 | (n-isomer); Suspected reprotoxic hazard,
Primary irritant (w/o allergic reaction), (iso-, primary):
Possible risk of forming tumors, Primary irritant (w/o allergic
reaction), (sec-, active primary-, and other isomers)
Primary irritant (w/o allergic reaction). Used as a solvent in
organic synthesis and synthetic flavoring, pharmaceuticals,
corrosion inhibitors; making plastics and other chemicals;
as a flotation agent. The (n-isomer) is used in preparation
of oil additives, plasticizers, synthetic lubricants, and as a
solvent. | | 輸送方法 | UN2811 Pentanols, Hazard Class: 3; Labels: 3-

Contact with strong oxidizers and hydrogen trisulfide may
cause fire and explosions. Incompatible with strong acids.
Violent reaction with alkaline earth metals forming hydrogen,
a flammable gas. | | 廃棄物の処理 | Dissolve or mix the material
with a combustible solvent and burn in a chemical incinerator
equipped with an afterburner and scrubber. All federal,
state, and local environmental regulations must be
observed. |
