In the preveous report, the relation between the chemical structure of some anionic surfactants and their antistatic capacities was studied. In this report, the relation between the chemical structure of cationic surfactants derived from long chain amines (primary, secondary, tertiary amine salts and quaternary ammonium salt) and their antistatic capacities was studied.
Investigated items with the chemical structure were as follows :
1. Effect of chain length of fatty residue which forms salt with each amine (C
0, C
2, C
6, C
12, C
18).
2. Effect of the classification of cationic surfants (primary, secondary, tertiary amine salt and quaternary ammonium salt).
3. Effect of the number of long chain residue which belongs to N of amine (1, 2, 3).
4. Effect of the chain length of long chain residue which belongs to N of amine (C
12, C
18).
5. Effect of the substitution of primary amine by long chain residue, and effect of the substitution of those long chain residues by methyl residue.
Item 25 were investigated in relation with item 1.
Results :
1. Primary, secondary, tertiary amine salt, even their structures are varied, are seriously inferior compared to the quaternary ammonium salt in antistatic capacity (10
810
12Ω to 10
610
7Ω).
2. The number of long chain residues which belong to N of amine roughly rules the type of relation curves, the electric resistance-chain length of salt forming fatty acid.
