Txoj kev:

4-Acetoxy-2,5-dimethyl-3-furanone tuaj yeem npaj los ntawm cov kauj ruam hauv qab no:

1. 2,5-Dimethyl-3-furanone yog reacted nrog acetic anhydride los tsim 4-acetoxy-2,5-dimethyl-3-furanone.

 

Cov ntaub ntawv kev nyab xeeb:

- Tsis txhob kov qhov muag, qhov ncauj, thiab qhov txhab qhib.

- DEET yog khaus thiab kev sib cuag nrog daim tawv nqaij ntev yuav ua rau khaus, ua xua, lossis tawv nqaij qhuav.
