I. 2-Methylfuran hpe galaw shapraw ai ladat
2-Methylfuran gaw ahkyak ai organic compound langai rai nna, tsi mawan, tsi mawan, manam pyaw ai baw ni hpe galaw ai hta grai lang ai. Shi hpe galaw shapraw ai ladat hta madung hku nna, laksan chemical reaction ni lawm ai. Kaja wa nga yang, furfural hpe n-gun n-gun hku lang nna, 2-methylfuran hpe hka n-gun shayawm ai, hka n-gun shayawm ai, hka n-gun shayawm ai hku nna shapraw ai.
Hydrogenation hpe shayawm ai aten hta, furfural gaw hydrogen hte n-gun dat langai a ntsa e shingdaw nna, tetrahydrofurfuryl alcohol hpe shapraw lu ai. Ndai lahkam a madung gaw, galai shai ai lam hte lata la ai lam hpe grau law hkra galaw lu na matu, htap htuk ai catalyst hte reaction masa ni hpe lata la ai lam rai nga ai. Dai hpang, tetrahydrofurfuryl alcohol gaw hka n-gun yawm mat nna, 2-methylfuran ngu ai n-gun hpe shapraw ya ai. Hpang jahtum, cyclization gaw, 2-methylfuran de galai shai kau ya ai.
II. 2-Methylfuran hpe hka ja ai ladat
-san seng ai 2-methylfuran hpe lu la na matu, hka hpe hka ja ai hku nna san seng hkra galaw ra ai. Distillation ngu ai gaw, garan ginhka ai ladat hpe lang ai rai nna, garan ginhka ai ladat gaw, kayau kaya ai hpe katsi shangun nna, hka lim ai shara n bung ai hka lim ai shara ni hpe shinggyin la lu ai.
2-methylfuran hpe galaw shapraw ai hta, hka ja ai column ni gaw ahkyak ai shara hpe hkam la nga ai. Distillation column a kata na hkrang masa hte bungli galaw ai masa ni gaw distillation effect hpe grai shadut ya ai. Madung hku tsun ga nga yang, distillation column ni hta, n-gun hte mass transfer hpe atsawm sha galaw lu na matu, n-gun rawng ai arung arai ni hpe atsawm sha matut mahkai lu na matu hte garan ginhka lu na matu galaw ra ai. Dai hta n-ga, bungli galaw ai nbung katsi ai hte n-gun hpe garan ginhka ai atsam hte arung arai san seng ai lam hpe jat wa hkra, hkrak tup hkang ra ai.
III. Distillation a akyu hte arung arai san seng ai lam hpe hkra machyi shangun ai lam ni
2-methylfuran hpe hka ja ai hta, ahkyak ai lam nkau mi gaw hka ja ai atsam hte arung arai san seng ai lam hpe shadut ya nga ai. Langai, raw materials ni a shingra tara hte atsam marai ni gaw distillation galaw na matu yak hkak ai lam hpe hkrak hkra machyi shangun ai. Raw materials ni hta n san seng ai lam law law lawm yang (sh) dai components ni hta boiling point bung ai rai yang, garan ginhka na matu grau yak wa ai. Dai majaw, raw material hpe galaw shapraw ai shaloi, san seng ai lam hpe grau nna galaw ra ai.
Lahkawng, bungli galaw na masa hpe lata ai lam mung ahkyak nga ai. Htap htuk ai bungli galaw ai nbung katsi ai hte n-gun atsam gaw distillation hpe grau kaja hkra galaw ya lu nna, product a san seng ai lam hpe mung grau kaja hkra galaw ya lu ai. Grai n-gun ja ai nbung laru gaw, arung arai ni hpe n-gun yawm shangun ai (sh) hten za shangun nna, grai n-gun yawm ai nbung laru gaw, garan ginhka ai lam n kaja ai hpe byin shangun chye ai. Dai majaw, bungli galaw ai lam hta kaja dik ai masa hpe tam ai gaw ahkyak dik rai nga ai.
Hpang jahtum, jak a bungli galaw ai lam hte masa gaw distillation a mahtai hpe mung hkra machyi shangun ai. Kaja ai nbung hte mass transfer jak ni gaw garan ginhka ai lam hpe grau kaja hkra galaw ya lu nna, n-gun hte arung arai ni hpe jai lang ai lam hpe shayawm ya lu ai. Dai hta n-ga, distillation galaw ai lam hpe ngang grin hkra galaw lu na matu, jak rung ni hpe gram lajang ai lam gaw ahkyak dik rai nga ai.
Tsun ga nga yang, 2-methylfuran hpe galaw shapraw ai ladat hte distillation hpaji hpe atsawm chye da ai gaw, kaja ai hte ngang grin ai galaw shapraw ai ladat hpe lu la nna, san seng ai arung arai hpe shapraw lu na re. Teng sha galaw shapraw ai hta, kaja dik ai galaw shapraw ai mahtai hpe lu la na matu, masa lam ni hte maren, process parameters hte arung arai ni hpe grau kaja hkra galaw nna, gram lajang ra ai.
