Dibutylene tetrafurfural Use and Manufacturing

Methods of Manufacturing

PRODUCED BY THE CONDENSATION OF BUTA-1,3-DIENE WITH 2-FURALDEHYDE (US PATENTS 2683511; 2934471)...

Uses

Used to repel cockroaches, mosquitoes, gnats, stable flies, horse blood flies, etc.

Formulations：

USED IN COMBINATION WITH OTHER REPELLENTS SUCH AS DEET & MGK REPELLENT 326 OR TOXICANTS IN LIQUID & PRESSURIZED SPRAYS.|USED AT 0.5% TO 1.25% BY WT WITH DIETHYLTOLUAMIDE & OTHER COMPOUNDS IN REPELLENTS FOR PERSONAL USE. USED AT 0.2% TO 0.25% WITH PYRETHRINS IN SPRAYS FOR PETS & SHOW ANIMALS & HORSES.|ACTIVE INGREDIENT IN WATER EMULSION OR OIL SPRAYS USED IN INSECT REPELLENTS (FINAL RECOMMENDED CONCN 0.2-0.4%).|A typical formulation contains 0.075% pyrethins, 0.15% piperonyl butoxide, and 1% 2,3:4,5-di(2-butenyl)tetrahydrofurfural.
