It has the melting point of −34 °C; boiling point of 164-168 °C at 0.7 mmHg and 365-367 °C at 1 atm; density of 0.810 g/mL at 20 °C; refractive index of n20/D 1.449; flash point of >230 °F; storage temperature is below 30 °C. Trioctylamine is easily soluble in chloroform but insoluble in water.
Food composition datasets (FCDBs) or food composition tables are resources that provide detailed food composition data (FCD) on the nutritionally important components of foods. FCDBs provide values for energy and nutrients including protein , carbohydrates , fat , vitamins and minerals and for other important food components such as fibre .
As foods vary by brands and stores, the figures should only be considered estimates, with more exact figures often included on product labels. For precise details about vitamins and mineral contents, the USDA source can be used. [1] To use the tables, click on "show" or "hide" at the far right for each food category.

Experts expect price hikes would lead some Americans to drop their coverage, while others would downgrade to cheaper plans. The Congressional Budget Office estimates that in total, 3 million more ...
Nutripoints [9] is a food-rating system which places foods on a numerical scale based on their overall nutritional value. The method is based on an analysis of 26 positive factors (such as vitamins, minerals, protein and fiber) and negative factors (such as cholesterol, saturated fat, sugar and sodium) relative to calories.
Triethylamine is prepared by the alkylation of ammonia with ethanol: [10]. NH 3 + 3 C 2 H 5 OH → N(C 2 H 5) 3 + 3 H 2 O. The pK a of protonated triethylamine is 10.75, [4] and it can be used to prepare buffer solutions at that pH.
