Kupu Whakataki
Ko te waikawa lactic ethyl ester he puhui waro.
Ko te Ethyl lactate he wai karekau me te kakara reka o te waipiro i te pāmahana rūma. He wairewa i roto i nga whakarewa pararopi penei i te waipiro, te etera, me te aldehydes, ka taea te tauhohe ki te wai hei hanga waikawa lactic.
He maha nga whakamahinga o te Ethyl lactate. I roto i te ahumahi kakara, he maha nga wa e whakamahia ana hei whakauru ki te whakarite i nga hua reka. Tuarua, i roto i te whakahiato waro, ka taea te whakamahi i te ethyl lactate hei whakarewa, hei whakakorikori, hei takawaenga.
E rua nga tikanga matua mo te whakarite i te ethyl lactate. Ko tetahi ko te tauhohe i te waikawa lactic me te waiwaro me te whai i te tauhohenga esterification ki te whakaputa ethyl lactate. Ko tetahi atu ko te whakahoki i te waikawa lactic me te acetic anhydride kia whiwhi ai i te ethyl lactate. Ko nga tikanga e rua me whai waahi te whakakorikori penei i te waikawa sulfuric me te anhydride sulfate.
Ko te Ethyl lactate he puhui iti-paitini, engari kei reira tonu etahi tikanga haumaru hei whai whakaaro. Ko te pa ki te ethyl lactate ka pawera te kanohi me te kiri, me mau nga taputapu whakamarumaru ina whakamahia ana. A ape i te rongo ki te mura ahi tuwhera me te wera nui hei aukati i te ngingiha me te pahū. I te wa e whakamahi ana, e pupuri ana ranei i te ethyl lactate, me tupato kia matara atu i nga matū muramura me nga matū waiora. Mena ka horomia te ethyl lactate, ka ngongohia ranei, me rapu wawe i te rongoa.
