Benzyl Ava: Meatotino, Sauniuniga, talosaga

alcohols ituaiga laau manogi - homologues benzene pogai, i le māeʻa lea ua suia le atomu hydrogen e hydroxy. I le taimi nei, o le alamanuia fagusausau ua lava e masani ona faaaogaina le ava malosi benzyl. O le fua faatatau o le lotoa faatusa i le toega māeʻa o se ava malosi ma benzene (phenyl) - S6N5SN2ON. faamatalaina isomerism alcohols ituaiga laau manogi filifili itu māeʻa ma tulaga vaega - Oi i le filifili hydrocarbon. Ava malosi i le tele o tulaga, na tuuina mai le igoa faatauvaa.

ava malosi Benzyl: auala o le mauaina o

alcohols ituaiga laau manogi i le setete saoloto ua lautele tufatufaina i le natura. O se tulafono faafoe, ua iloa mai i latou i le suauu taua. na synthesized ava malosi Benzyl mai halogenated homologues benzene, lea o lo o faasa le halogen i se filifili itu. O nei alcohols ese mai le phenols luga o mea uma ona ua latou le tuuina meatotino acidic. e maua foi le ava malosi Benzyl mai mea mata faalenatura, lea o loo esters. Mulimuli ane, sa faapea ona maua na aumaia i alcohols ituaiga laau manogi. e latalata alcohols ituaiga laau manogi e alcohols aliphatic: e ala i le gaoioiga o alkali alkoxides uamea e fai ai; e oxidation, e faalagolago i luga o le fausaga, e liua i le tutusa aldehydes po ketones; E faigofie ona pepa ethers ma esters.

meatotino faaletino o alcohols

O le sui muamua o le faasologa homologous o alcohols acyclic - suavai, ma alcohols maualuga - solids. homologs Sili (methanol, ethanol, propanol) i ai se manogi o le ava malosi, auala (isopropanol, butanol, isobutanol, pentanol, hexanol) - suauu fusel, maualuga - e leai se manogi. Alcohols se maualuga tulaga pupuna, lea e fesootai ma le mafutaga o le molecules e ala i noataga hydrogen. O le tele o nei mea ma isi meatotino physico-vailaau o alcohols eseese lava ma faateleina mamafa molecular.

E tatau ona amanaia le mea moni e faapea o le suiga o le ava malosi mai le suavai i gaseous tulaga (i pupuna) solia le fusi hydrogen. O le ultraviolet mitiia fusi o alaleo o loo i ai se vaega i le itulagi 150-200 nm. X-ray ma electron diffraction mafai ona fuafuaina le tulimanu o le coupling nonlinear F-I-N o 110 ° 25 '. A o le alcohols ituaiga laau manogi, ua ona latou faamatalaina i le meatotino lava lea e tasi e pei o lena o alcohols acyclic. O nei tuufaatasi o le lelei po o le le soluble i le vai, lelei - i solvents faatulagaina. O le manatu pupuna tele maualuga atu nai lo le arene tutusa. O le vaega aafiaga i totonu o le spectra ultraviolet ma infrared tutusa alcohols aliphatic.

meatotino vailaau o alcohols ituaiga laau manogi

O nei tuufaatasi le meatotino vailaau lava e tasi e pei o le alcohols aliphatic. Latou fausia alkoxides, ethers ma esters, halogenated i le filifili itu, ma ina ua le oxidation - ketones, aldehydes, ma acids ituaiga laau manogi. Lē gata i lea, e mafai ona faaalia nei alcohols meatotino arenes. Mo se faataitaiga, e mafai ona latou tali atu vaega faaogatotonu len¯ao benzenovogo - halogenation, nitration, sulfonation, ma hydrogenation, ma isi

Benzyl ava malosi - mautu, lava soluble i ethanol, le lelei - i le vai, melts i 15,3 ° C, maʻi fulafula i 205,8 ° C. Saunia lona hydrolysis alkaline o chloride benzyl e le tali benzaldehyde ma formaldehyde i le afioaga o hydroxide sodium, o nisi o taua suauu ma balms faalenatura. Faaaogaina o manogi, manogi loka, o le mafai ona totogi aitalafu i le alamanuia fagusausau.

ava malosi Beta-phenylethyl - melts mausali i le 27 ° C ma le maʻi fulafula i le 222 ° C, soluble i ethanol. Aofia ai i le lanu piniki, kelove suauu taua. O le faaaogaina o mea o ituaiga laau manogi, lea ei ai le manogi o le rosa. Foi, o se mea faaaogaina masani i le alamanuia fagusausau ma meaai.

ava malosi Cinnamic - melts mausali i le 33 ° C, faigofie soluble i ethanol. Sa i ai faapitoa i le tulaga o ethers i suauu taua, resins manogi, balsams. mea o ituaiga laau manogi ma hyacinth manogi o loo faaaogaina i le alamanuia fagusausau, ma pei o mea e masani ona maua mo le tuufaatasia o le tele o mea odorous.
