alkyl chloride. An emulsion is formed. This test is reliable only for alcohols that are fairly soluble in water. Tertiary Alcohols React immediately to form an emulsion of the alkyl halide and water (cloudy solution). Secondary Alcohols React in 5-10 minutes. Heating in warm water and shaking is sometimes necessary with water-insoluble alcohols.

Alcohol properties (video) | Khan Academy
So the butanol right here is soluble, but not miscible in water. If you have too much of the butanol, all of a sudden, some of it will not actually be able to be dissolved. If this was a decanol or something with a really long carbon chain, then of course, it's …
Alcohol
Small alcohols are completely soluble in water; mixing the two in any proportion generates a single solution. However, solubility decreases as the length of the hydrocarbon chain in …
Poisoning by alcohols and glycols
Toxic alcohols account for only around 0.5% of poisoning cases but represent 3–5% of enquiries to the UK National Poisons Information Service. ... Ethanol rapidly distributes in the water component of tissues, is not fat soluble and does not bind to proteins. Ethanol is subject to metabolism by certain alcohol dehydrogenase (ADH) …
Alcohol
Alcohol - Boiling Point, Solubility, Flammability: Most of the common alcohols are colourless liquids at room temperature. Methyl alcohol, ethyl alcohol, and isopropyl alcohol are free-flowing liquids with fruity odours. The higher alcohols—those containing 4 to 10 carbon atoms—are somewhat viscous, or oily, and they have heavier …

Alcohols and Ethers
When the hydrocarbon chain is short, the alcohol is soluble in water. There is no limit on the amount of methanol (CH 3 OH) and ethanol (CH 3 CH 2 OH), for example, that can dissolve in a given quantity of water. As the hydrocarbon chain becomes longer, the alcohol becomes less soluble in water, as shown in the table below.
