1-Decanol (also decyl alcohol or capric alcohol) is a long-chain alcohol with the semi- structural formula C 10 H 21 OH.
Presentation and extraction
The technical synthesis can take place via the oxo synthesis and subsequent hydrogenation . 1-Decanol can also be obtained by hydrogenating the fatty acid capric acid (C 9 H 19 COOH). Therefore the compound is also counted among the fatty alcohols .
properties
1-Decanol is a colorless, oily, sweet-smelling liquid at room temperature and has a slightly irritating effect locally. It has a molar mass of 158.28 g · mol −1 , melts at 7 ° C and boils at 230 ° C. The density of 1-decanol is 0.83 g cm −3 . 1-Decanol dissolves only minimally in water, but very well in alcohols and ethers .
The compound forms flammable vapor-air mixtures at higher temperatures. The compound has a flash point of 108 ° C. The lower explosion limit is around 0.6% by volume (40 g / m 3 ). The ignition temperature is 250 ° C. The substance therefore falls into temperature class T3.
use
The alcohol is used as a wetting agent , extraction agent and solvent . Esters of the compound are used in paints and plastics. It is also used to make special perfumes.
Safety instructions / toxicity
In 2012, 1-decanol was included in the EU's ongoing action plan ( CoRAP ) in accordance with Regulation (EC) No. 1907/2006 (REACH) as part of substance evaluation . The effects of the substance on human health and the environment are re-evaluated and, if necessary, follow-up measures are initiated. Ingestion of 1-decanol was driven by concerns about high (aggregated) tonnage, other exposure / risk-based concerns, other hazard-related concerns and widespread use. The re-evaluation took place from 2012 and was carried out by Italy . A final report was then published.
