| | 2,2-ジメチル-1-プロパノール Usage And Synthesis |
| 外観 | 白色～ほとんど白色, 結晶又は塊 | | 溶解性 | 水に可溶 (約3.5%, 25℃), アルコール, エーテルに易溶。 | | 用途 | 有機合成原料、溶剤。 | | 化学的特性 | Amyl alcohols (pentanols) have eight isomers.
All are flammable, colorless liquids, except the isomer 2,2-
dimethyl-1-propanol, which is a crystalline solid. | | 化学的特性 | colorless waxy crystalline solid | | 使用 | - 2,2-Dimethyl-1-propanol can be used in the synthesis of surfactant that stabilize reduced graphene oxide (rGO) dispersion.
- Biodiesel containing branched-chain esters prepared by the transesterification of vegetable oils with 2,2-dimethyl-1-propanol has been reported to show lower crystallization temperature when compared to methyl and ethyl ester counterparts.
| | 使用 | It is used in the Mitsunobu reaction of methyl salicylate coupling of sterically hindered substrates. | | 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-
Flammable liquid. UN1987 Alcohols, n.o.s., Hazard Class:
3; Labels: 3-Flammable liquid. | | 純化方法 | It is difficult to distil because it is a solid at ambient temperatures. Purify it by fractional crystallisation and sublimation. [Beilstein 1 IV 1690.] | | 不和合性 | Forms an explosive mixture with air.
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. |
