Beschreibung
Zusammenfassung:	The invention discloses a high-temperature-yellowing-resistant glycerol. The preparation method comprises the following steps: a. taking a right amount of glycerol with the purity of 95-98%; and b. adding right amounts of sodium hypochlorite and additive into the glycerol, and stirring uniformly under heating conditions to obtain the high-temperature-yellowing-resistant glycerol. The high-temperature-yellowing-resistant glycerol is prepared from the following raw materials in percentage by weight: 90-99% of glycerol, 1-1.5% of sodium hypochlorite and the balance of additive. The additive comprises any one or combination of the following raw materials: nano titanium dioxide, hexamethyl phosphoric triamide, distearyl thiodipropionate and water. The production technique of the high-temperature-yellowing-resistant glycerol is simple, and is low in production cost and simple to operate. When the high-temperature-yellowing-resistant glycerol is combined with the resin and the like to produce a paint, the paint can
