摘要

Defreeze-37 comprises (in %) ammonium sulfate (45), calcium chloride (20), magnesium chloride (15), urea (10), calcium sulfate (5) and magnesium sulfate (5), where at least one above components of the mixture is removed, the weight or volume fraction of at least one of the referenced components is changed, and e.g. alcohol, mono-, di- and trivalent salts, glycerin and/or glycerol, sodium hydroxide, ketone compounds, aldehyde compounds, sugar-containing compounds, dimethylformamide or dimethyl sulfoxide, and nitrates, nitrites, chlorides, bromides or iodides are added for mixing defreeze-37. Defreeze-37 comprises (in %) ammonium sulfate (45), calcium chloride (20), magnesium chloride (15), urea (10), calcium sulfate (5) and magnesium sulfate (5), where at least one component of the mixture is removed, the weight or volume fraction of at least one of the component is changed, and alcohol, mono- and divalent salts comprising chlorine, fluorine, bromine or iodine and trivalent salts, glycerin and/or glycerol, sodium hydroxide, metal-hydroxy compounds of (metal OH (n)), ketone compounds, aldehyde compounds, different sugars and sugar-containing compounds, dimethylformamide or dimethyl sulfoxide, and nitrates, nitrites, chlorides, bromides or iodides are added for mixing defreeze-37.
