1,3-dithiolethione - Reference Information
| Use | 1, 3-disulphurine-2-thiol Chinese alias thiovinylene carbonate, can be used as a crosslinking agent. |
| application preparation | 1, 3-disulphate-2-thioin can be used as a cross-linking agent for the preparation of an aldehyde-free soybean powder adhesive, 100 parts of water, 0.7 parts of sodium hydroxide, 1.7 parts of urea, 2 parts of sodium silicate to prepare the modifier solution, and then add 40 parts of soybean powder to the modifier solution (crude protein content of 55%, crude protein in the aqueous protein content of 92%) after stirring for 15min under the condition of 800r/min until no dry powder appeared, and after 50min, add 25 parts of ethylene trithiocarbonate (1, 3-bisulphate -2-sulfur), 20 parts of polyamine amide epichlorohydrin, 0.8 parts of oxalic acid, 1 part of sodium sulfite and 0.5 part of citric acid were added and stirred for 7min at 1500r/min, the liquid aldehyde-free soybean adhesive was obtained. The liquid aldehyde-free soybean adhesive is passed through a pressure spray dryer with a rotating speed of 9000r/min, an inlet air temperature of 150 ℃/min, an outlet temperature of 65 ℃/min, and a drying time of 8min, A light yellow aldehyde-free soybean powder adhesive was obtained. |
