Usage

General Description

4-octadecylmorpholine is a chemical compound with a molecular formula of C22H45NO. It is a morpholine derivative with an octadecyl group attached to the nitrogen atom. 4-octadecylmorpholine is often used as a corrosion inhibitor in water treatment systems and in the production of metalworking fluids. It is also used as an intermediate in the synthesis of other chemicals. 4-octadecylmorpholine is known for its ability to form a protective film on metal surfaces, thereby preventing corrosion and rust formation. It is classified as a hazardous substance and should be handled with care and proper safety precautions.

Nematocidal activity of long alkyl chain amides, amines and their derivatives on dog roundworm larvae

The nematocidal activity of amides and amines having a long alkyl chain against the second-stage larva of dog roundworm, Toxocara canis, was examined. Long chain acyl amides with smaller substituents on the nitrogen showed stronger activity and the activity of cyclic amine amides was stronger than that of acyclic ones. In a series of homologous amides, the activity was dependent on the alkyl chain length: it reached a maximum at an optimal chain length and decreased in both shorter and longer homologues. The relationship between the activity and hydrophobicity of the homologues was analysed by the use of the bilinear model. The hydrophobicity of a compound, which gives a maximal activity, was similar for all neutral amides, but amides which have an additional amine group in the molecule had different values. Tertiary amines and their salts having a long alkyl chain also showed nematocidal activities comparable to those of the corresponding amides. The salts killed the larva at concentrations lower than their critical micell concentration, suggesting that they behave as a single molecule for the nematocidal action.
