Phenethyl alcohol, or 2-phenylethanol, is an organic compound with the chemical formula C 6 H 5 CH 2 CH 2 OH. It is a colourless liquid with a pleasant floral odor. It occurs widely in nature, being found in a variety of essential oils. It is slightly soluble in water (2 ml per 100 ml of H 2 O), but miscible with most organic solvents.
The following chart shows the solubility of various ionic compounds in water at 1 atm pressure and room temperature (approx. 25 °C, 298.15 K). "Soluble" means the ionic compound doesn't precipitate, while "slightly soluble" and "insoluble" mean that a solid will precipitate; "slightly soluble" compounds like calcium sulfate may require heat to precipitate.

When necessary, the position of the hydroxyl group is indicated by a number between the alkane name and the -ol: propan-1-ol for CH 3 CH 2 CH 2 OH, propan-2-ol for CH 3 CH(OH)CH 3. If a higher priority group is present (such as an aldehyde , ketone , or carboxylic acid ), then the prefix hydroxy- is used, [ 19 ] e.g., as in 1-hydroxy-2 ...
There is an apoplastic immune system, but pathogens with effectors can modulate or suppress the host’s immune responses. This is known as effector-triggered susceptibility. [ 12 ] Another factor in pathogens’ frequent colonization of the apoplast is that when they enter from the leaves, the apoplast is the first thing they come across. [ 13 ]
Colloids are formed by phase separation, though not all phase separations forms colloids - for example oil and water can form separated layers under gravity rather than remaining as microscopic droplets in suspension. A common form of spontaneous phase separation is termed spinodal decomposition; it is described by the Cahn–Hilliard equation.
RCH 2 OH + n C 2 H 4 O → RCH 2 (OCH 2 CH 2) n OH. The resulting fatty alcohol ethoxylates are important surfactants. Another large class of surfactants are the sodium alkylsulfates such as sodium dodecylsulfate (SDS). Five million tons of SDS and related materials are produced annually by sulfation of dodecyl alcohol and related fatty ...
