Melamine formaldehyde is affected by alkalis and concentrated acids–such as sulphuric acid (H2SO4) and oxalic acid (H2C2O4). Melamine formaldehyde utensils are not microwave safe. They absorb radiation, which
It can also react very exothermically and possibility of spitting with halogens and strong acids. In an alkaline environment, the compound is likely to react violently. In addition, the compound can form toxic products such as n-nitrosamines when combined with nitrous acid as well as oxygen, ...
Melamine formaldehyde is affected by alkalis and concentrated acids–such as sulphuric acid (H2SO4) and oxalic acid (H2C2O4). Melamine formaldehyde utensils are not microwave safe. They absorb radiation, which causes their polymer bonds to break down and percolate toxins into the food. Melamine for...
Dimethylamine hydrochloride has been used in the preparation of hexamethylmelamine-methyl-14C. It has also been used to prepare the standard solution of methylamine (MA), dimethylamine (DMA), trimethylamine (TMA), and trimethylamine-N-oxide (TMAO) while determing methylamines and trimethylamine-N-...
