Quid est surfactant?

SurfactantsSunt componit quod potest significantly reducere superficiem tensio vel interfacial tensio inter duas liquores, inter liquidum et Gas, et inter liquidum et solidum. Et Molecular structuram de Surfactants est Amphiphilic: unum finem est hydrophilic coetus et alia finis est hydrophobic coetus; Et Hydrophilic coetus est saepe in Suspendisse coetus, ut carboxylic acidum, sulfonic acidum, sulphuric acidum, amino et group et ejus sal, hydroxyl, amare hydrophilic coetibus, etc. Dum Hydrophobic coetus est saepe a non-Suspendisse hydrocarbon torquem, ut hydrocarbon catena cum plus quam VIII carbonis atomorum. SURFABTANTS dividitur in IONIC SURFABTANTS (including CENTIO SURFABTANTS, anionic surfactants, amphoteric surfactants), nonionic surfactants, compositis saltu, alius surfactants, etc.

Chemical structuram

Surfactant molecules have unique amphiphilicity: one end is a hydrophilic polar group, referred to as a hydrophilic group, also known as an oleophobic group or an oleophobic group, such as -OH, -COOH, -SO3H, -NH2. Propter hoc genus coetus brevis in longitudinem, est aliquando figuratively dicitur a hydrophilic caput. Et alia finis est a non-Suspendisse coetus quod est lipophilic, etiam notum est Hydrophobic coetus vel aqua-repellent coetus, ut r- (Alkyl) et ar- (Aryl). Propter hoc genus coetus brevis est aliquando figuratively vocavit Hydrophobic cauda. Two types of molecular groups with completely opposite structures and properties are located at both ends of the same molecule and connected by chemical bonds, forming an asymmetric, polar structure, thus giving this type of special molecule the characteristics of being both hydrophilic and lipophilic, but not overall hydrophilic or lipophilic. Hoc unique structuramsurfactantssolet dicitur "Amphiphilic structuram" et surfactant moleculis ideo saepe vocatur "Amphiphilic moleculis".
