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.
Food should be removed from "the danger zone" (see below) within two-four hours, either by cooling or heating. While most guidelines state two hours, a few indicate four hours is still safe. T: Temperature Foodborne pathogens grow best in temperatures between 41 and 135 °F (5 and 57 °C), a range referred to as the temperature danger zone (TDZ).
