Tab sis ib zaug nws tsis yog cov ntaub ntawv, thiab nyob rau organic Science News for KIDS los paub me ntsis.

Cia peb kawm seb yuav ua li cas hloov zuj zuj kauj ruam yog kauj ruam cov keeb kwm ntawm cov organic Science News for KIDS.

1. Lub sij hawm ntawm txoj kev loj hlob kom txog thaum lub XIV xyoo pua, hu ua ntuj.

2. XV - XVII caug xyoo - thaum pib ntawm txoj kev loj hlob los yog iatrochemistry alchemy.

3. Xyoo pua XVIII - XIX - lub dominance ntawm lub hom phiaj ntawm vitalism.

4. XIX - XX caug xyoo - intensive kev loj hlob, kev theem.

Pib los yog tej yam ntuj tso theem ntawm kev loj hlob ntawm cov organic Science News for KIDS

Qhov no theem muaj cov heev tshwm sim los ntawm lub tswvyim ntawm tshuaj paus. Thiab lub hauv paus pib mus kom deb li deb rov qab raws li ancient Rome thiab tim lyiv teb chaws, uas yog muaj lub peev xwm cov neeg kawm tau mus ua dyes rau coloring khoom thiab khaub ncaws los ntawm tej yam ntuj tso raw cov ntaub ntawv - nplooj thiab stems ntawm nroj tsuag. Cov no yog cov indigo, muab lub sib sib zog nqus xim xiav, thiab alizorin tseg cia tag nrho cov hluas thiab txaus nyiam ntxoov txiv kab ntxwv thiab liab. Unusually nimble inhabitants ntawm txawv haiv tib lub sij hawm kuj kawm tau li cas kom tau txais cov vinegar, yuav ua rau dab los ntawm sucrose thiab cov hmoov txhuv nplej-muaj tshuaj tsob nroj keeb kwm.

Nws yog lub npe hu hais tias ib tug ntau heev zaub mov nyob rau hauv daim ntawv thov ntawm no cov keeb kwm lub sij hawm twb tsiaj, zaub roj thiab resins uas yog siv los ntawm chefs thiab kho neeg lub siab. Thiab kuj nyob rau hauv lub neej txhua hnub ntawm ntau yam tshuaj lom nyob nruj nreem raws li lub ntsiab riam phom vnutriusobnyh kev sib raug zoo. Tag nrho cov tshuaj cov khoom ntawm cov organic Science News for KIDS.

Tab sis, hmoov tsis, xws li, lub tswvyim ntawm "Science News for KIDS" tsis muaj nyob, thiab kawm txog tej yam nyob rau hauv thiaj li yuav meej lub zog thiab muaj pes tsawg leeg tsis tshwm sim. Yog li ntawd, lub sij hawm no yog hu ua txawj. Tag nrho cov discoveries twb random, unfocused xwm ntawm cov neeg tseem ceeb. Qhov no txuas ntxiv kom txog thaum lub tom ntej no xyoo pua.

iatrochemistry lub sij hawm - ib tug pheej pib loj hlob

Xwb, nws yog nyob rau hauv lub XVI - XVII centuries pib los mam direct sawv cev ntawm Science News for KIDS raws li ib tug science. Los ntawm lub chaw ua hauj lwm zaum tej lub sij hawm tau tau organic tshuaj yees yooj yim apparatus rau distillation thiab sublimation ntawm tshuaj siv ib tug tshwj xeeb tshuaj hlab ntsha rau crushing tshuaj mus rau lub sib cais ntawm tej yam ntuj tso khoom xyaw.

Lub ntsiab kom pom tseeb ntawm lub sij hawm yog cov tshuaj. Lub siab xav tau tus tsim nyog cov tshuaj tau coj mus rau lub fact tias cov nroj tsuag sawv tseem ceeb roj thiab lwm yam nyoos cov khoom xyaw. Yog li, Karl Scheele twb tau ob peb organic acids ntawm zaub raw cov ntaub ntawv:

• malic;
• txiv qaub;
• gallic;
• mis nyuj;
• oxalic.

Nyob rau hauv txoj kev tshawb no ntawm cov nroj tsuag thiab qhov qee ntawm cov acids paub txog coj 16 xyoo (1769 rau 1785). Qhov no yog qhov pib ntawm txoj kev loj hlob, nteg lub lub hauv paus ntawm organic Science News for KIDS, uas yog ncaj qha raws li ib tug ceg ntawm Science News for KIDS tau raug pom tias thiab muaj npe tom qab ntawd (thaum ntxov XVIII century).

Nyob rau hauv tib lub sij hawm nruab nrab GF tseem ceeb Rueil muaju ntawm uric acid ntawm urea. Lwm yam chemists succinic acid twb tau los ntawm amber, tartaric acid. Nyob rau hauv kev siv muaj xws li ib txoj kev ntawm qhuav distillation ntawm nroj tsuag thiab tsiaj cov ntaub ntawv, los ntawm cov uas yog tau acetic acid, diethyl ether, ntoo cawv.

Yog li pib lub intensive kev loj hlob ntawm cov organic tshuaj lag luam nyob rau hauv lub neej yav tom ntej.

Vis vitalis, los yog "lub neej quab yuam"

XVIII - XIX xyoo pua rau cov organic Science News for KIDS heev ob-fold: nyob rau hauv ib tes, muaj ib tug xov tooj ntawm discoveries uas muaj zog heev muaj nqis. Nyob rau hauv lwm yam, ib tug ntev lub sij hawm, txoj kev loj hlob thiab txuam nrog ntawm cov txuj ci thiab yog cov tswv yim inhibited lub hom phiaj ntawm vitalism.

Qhov no kev tshawb xav coined thiab teev tseg cov ntsiab Jens Jakobs Berzelius, uas nyob rau tib lub sij hawm nws nws tus kheej tau muab, thiab lub ntsiab txhais ntawm cov organic Science News for KIDS (lub caij nyoog lub xyoo yog tsis paub, los yog 1807 los yog 1808). Raws li cov kev cai ntawm no ziag no, cov organic tshuaj peev xwm yuav tsim nyob rau hauv tsuas muaj sia nyob (cov nroj tsuag thiab tsiaj txhu, xws li tib neeg), raws li cov tsuas nyob beings muaj ib tug tshwj xeeb "lub neej quab yuam" uas tso cai rau cov tshuaj ua. Thaum inorganic tshuaj tau organic kiag li tsis yooj yim sua, txij li thaum lawv cov khoom tswg, uas tsis yog-flammable, tsis muaj vis vitalis.

Cov tib zaum thawj kev faib ntawm tag nrho cov paub thaum lub sij hawm ntawm lub tebchaw nyob rau hauv lub inorganic (non-nyob, tag nrho cov tshuaj zoo li cov dej thiab ntsev) thiab organic (nyob, cov neeg uas zoo ib yam li txiv roj roj thiab suab thaj) tau npaj siab. Tsis tas li ntawd Berzelius thawj xws hais tias xws li organic Science News for KIDS. Kev Txiav Txim no yog: ib tug seem ntawm Science News for KIDS uas kawm cov tshuaj muab los ntawm muaj sia nyob.

Thaum lub sij hawm lub sij hawm no, zaum tau yooj yim los siv hloov dua siab tshiab ntawm cov organic tebchaw rau hauv inorganic, e.g., los ntawm combustion. Txawm li cas los, tau reconversion ntawm dab tsi yog tsis paub tsis tau.

Hmoo yuav muaj nws, hais tias nws yog tus menyuam kawm ntawv Jens Berzelius Fridrih Veler pab mus rau thaum pib ntawm lub cev qhuav dej ntawm lub hom phiaj ntawm nws tus kws qhia ntawv.

German tus paub txog kev ua hauj lwm nyob rau hauv cyanide tebchaw thiab nyob rau hauv ib tug ntawm lub thwmsim ua kom tau muaju tswj Zoo li uric acid. Raws li ib tug tshwm sim, ib tug ntau txhij txhua txoj kev tshawb no nws pom tias yeej muaj kev tswj kom tau organic teeb meem los ntawm inorganic, tsis muaj vis vitalis. Tsis muaj teeb meem li cas skeptical Berzelius, nws twb yuam kom lees no undeniable fact. Yog li ntawd nws twb hais txog cov thawj tshuab mus rau lub vitalistic views. Lub keeb kwm ntawm cov organic Science News for KIDS pib nce zog.
