Anhydride Acetic: meatotino, sauniuniga ma le faaaogaina

Anhydrides o acids carboxylic - o oloa o dehydration o le molecules. O loo faamatalaina i le isomerism radicals biosoedineny. Ina ua faaigoaina anhydrides acid carboxylic sili ona masani ona faaaogaina nomenclature talafaasolopito (f.t.t., anhydride, acid acetic, anhydride maleic, ma isi). I le taimi o le faaopoopoga o acids dehydrating sui carboxylic (e masani phosphorus oxide) e tupu o latou dehydration, e mafua i le faavaega o anhydrides carboxylic acid.

anhydride Acetic: Sauniuniga o

O le ulutala lotoa maua e mafai ona fufuluina tele o auala. Mo lona tuufaatasia sili ona masani faaaogaina oxide phosphorus, o se sui sooupu dehydrating malosi tele. E i ai foi isi auala mo le tuufaatasia o anhydride. Mo se faataitaiga, e mafai ona maua anhydride acetic i lalo o le gaoioiga o phosphate o le anhydride acid acetate. ua faaopoopo le faagasologa cooling dropwise SN3SOS1 o se tasi vaega i le vaega dewatered ma mago lelei acetate sodium-acid. O le taunuuga o le suia na faamafanafana moderately ma sa aveesea ai le anhydride acetic synthesized i se tapu oneone ma faamamaina e distillation. Ona o se taunuuga o le faagaoioiga gaosia malosi manogi manaia acid acetate suavaia.

anhydride Acetic, ma maualalo molecular mea - suavaia ma se manogi maai, O lona insoluble i le vai, faigofie soluble i le tele o mea faatulagaina. E tatau ona matauina e le anhydrides o maualuga acids carboxylic (aemaise le faatapulaaina) - solids odorless. Latou vevela pupuna tele maualuga atu nai lo le tutusa acids carboxylic.

anhydride Acetic: Meatotino oona

O lenei lotoa o loo faaaoga masani mo le tele o tagata o vasega eseese o mea faatulagaina e auala o tuufaatasia faatulagaina. I le tali mai a le anhydrides i le vai e tuuina atu molecules e lua o le acid tutusa.

Amonoliz anhydrides e taitai atu ai i le faavaega o amides ma ammonium masima o le tutusa acids carboxylic. O le tali faaaogaina mo le mauaina o alkoliza ma anhydrides esters.

o loo faaaogaina anhydride Acetal o le dehydrating ma acetylating sooupu i totonu o le atsetiltselyulozy faagasologa gaosiga, acetate vinyl, vailaau, dimethylacetamide, colorants, mea o ituaiga laau manogi, ma isi ua aldehyde Acetate oso ai le inoino i le tamaitusi respiratory, mata, ma mafua ai ona mu le paʻu.

acetate Cellulose maua ona o le gaoioiga i luga o le anhydride acetate cellulose i le afioaga o se vaega taua (sulphate acid). saunia acetylation atoatoa diacetates mono- ma cellulose. triacetate Di- ma cellulose faaaogaina i le tuuina atu o silika acetate. Mo lenei faamoemoe ua faataapeina i latou i se tuufaatasiga o acetone ma ethanol (85:15) po o le i acetone mama. e maua fofo Viscous ua extruded ala faamama faapitoa. fasi pepa manifinifi o le vaifofo soloia ma liliu i yarns, lea o loo faaaogaina mo le tuuina atu o ituaiga eseese o vulu o alava gaosi.

O le talosaga tau alamanuia o loo faaaogaina ma le isi anhydrides. anhydride Maleic - mea crystalline, lelei soluble i le vai ma i acetone, melts i 52,85 ° C. E masani lava, ua saunia i lenei mataupu mai acid maleic. Faaaogaina i le tuuina atu o iniseti faalafua, polyester ma resins alkyd. ua tuuina anhydride Phthalic ona o le oxidation o naphthalene. ua faaaoga e le gata mo le tuufaatasia o le faalauiloaina tuputupu ae, insecticides, faapea foi ma nisi o fualaau. anhydride Phthalic - crystalline mautu ma se faaliusuavai tulaga o le 128 ° C. Fai mai o loo faaaogaina anhydride e maua Phenolphthalein (faailoga ma medicament). o loo faaaogaina lenei anhydride mo le repellents gaosia (dimethyl phthalate).
