The electrophilic substitution reaction between benzene and ethanoyl chloride What is acylation? An acyl group is an alkyl group attached to a carbon-oxygen double bond. If R represents any alkyl group, then an acyl group has the formula RCO-.he facts The most reactive substance containing an acyl group is an acyl chloride (also known as an acid chloride). These have the general formula RCOCl. Benzene is treated with a mixture of ethanoyl chloride, CH3COCl, and aluminium chloride as the catalyst. A ketone called phenylethanone is formed.
Non-ionic Surfactants Structure Surfactants which that are charge neutral on both the hydrophilic end and the lipophilic end are named, logically, non-ionic. The hydrophile is produced from a polyethylene oxide (PEO) chain, and the lipophile from an alkyl (saturated hydrocarbon) alcohol. more common type of defoamer for emulsion PSAs is principally a dispersion of silica particles, mineral oil, and a dispersing aid such as non-ionic surfactant. Tiny dispersed oil droplets carry silica to the bubble where the jagged particle physically disrupts the cell wall (Figure 9).
