Yore mi ketho piny ma tek I 2014, yub pa hydroxypropyl acrylate HPA ma tiyo ku piny ma tek calu catalyst jukoro pi tyen acel i pacu man woko. Kadi bende solid base catalysts loyo peko pa catalysts macon, calu ve tic ma tek i ngei tic man nyayu piny ma rac, i saa mi timo tic, pores moko pa solid base catalysts jugwoko ku molecules madongo, ma ketho catalytic active sites doko nok man kelo yield ma nok pa hydroxylapyl HPA. Tic ku jamb tic ma tek i yubu pa hydroxypropyl acrylate mitu timo sayusac mukende.

Ku timo maber man timo filim, Hydroxypropyl Acrylate HPA medo tic man bedo pa piny matung tung.
