Abstract

Aliphatic amines with chain lengths from C2 to C18 were investigated for their effect on the diffusion of [3H]-sorbitol, [14C]-glycerol, 36Cl- and 86Rb+. Before amine application, enamel was pretreated with a phytate solution. C12-C18 amines reduced the rate of diffusion to values of about 20-30 per cent of the values found before treatment. Amines with chain lengths below C12 were less effective. The presence of an unsaturated carbon-carbon bond (C18:1) seems to promote the absorbance of the amine to enamel.

摘要

研究了链长从C2到C18的脂肪胺对[3H] -山梨醇、[14C] -甘油、36Cl-和86Rb+扩散的影响。在施加胺之前，先用植酸溶液对牙釉质进行预处理。C12 - C18胺将扩散速率降低至处理前值的约20 - 30%。链长低于C12的胺效果较差。不饱和碳 - 碳键（C18:1）的存在似乎促进了胺对牙釉质的吸附。
