Imibuzo Evame Ukubuzwa (FAQs)

Q1: Injani ukubonakala kwe-p-Hydroxybenzaldehyde?
Ngokuvamile iyimpushana yekristalu emhlophe ukuya kokumhlophe. Ukuhlanzeka okuphansi noma okugugile kungase kubonakale kuphuzi ngokuphaphathekile kuya ku-beige okhanyayo. Ifomu elihlanzekile liqukethe amakristalu afana nenaliti.

Q2: Ingabe i-p-Hydroxybenzaldehyde iyancibilika emanzini?
Incibilika kancane emanzini (cishe 8.45 g/L ku-25 °C). Ukuncibilika kukhula kakhulu kuzincibilikisi zemvelo ezifana ne-ethanol, i-methanol, i-acetone, ne-diethyl ether.

Q3: Kufanele ngiyigcine kanjani i-p-Hydroxybenzaldehyde?
Gcina esitsheni esivalwe ngokuqinile kude nokukhanya, ukushisa, kanye nomswakama. Gcina endaweni efudumele (15-30 ° C) endaweni eyomile engenawo umoya. Gwema ukuthintana nama-oxidizing agents aqinile nezisekelo eziqinile. Ngaphansi kwesitoreji esifanele, impilo yeshalofu idlula izinyanga ezingama-24.

Q4: Uyini umehluko phakathi kwe-p-hydroxybenzaldehyde ne-vanillin?
I-Vanillin (4-hydroxy-3-methoxybenzaldehyde) ineqembu elengeziwe le-methoxy endaweni ye-meta. I-p-Hydroxybenzaldehyde iyisandulela esiqondile se-vanillin nge-methylation. Inephrofayili yephunga eligcwele i-aldehyde uma iqhathaniswa nenothi elimnandi le-vanilla le-vanillin.

Q5: Ingabe i-p-hydroxybenzaldehyde iyingozi?
Ihlukaniswa njengesikhumba nokucasula kwamehlo (H315, H319). Ukuhogela uthuli kungase kubangele ukucasuka kokuphefumula. I-PPE evamile (ijazi lelebhu, amagilavu, izibuko zokuphepha) kanye nokukhipha umoya kufanele kusetshenziswe. Ayihlukaniswa njenge-carcinogenic, mutagenic, noma enobuthi ekukhiqizeni.

Yebo. I-Aozunchem inikeza kokubili ibanga lezimboni (≥99%) kanye nebanga lokuhlanzeka okuphezulu (≥99.5% nge-HPLC) kwezicelo zemithi neze-elekthronikhi. Sicela ucacise imfuneko yakho lapho ucela ikhotheshini.

Q7: Yiziphi ukusabela ezingatholwa yi-p-hydroxybenzaldehyde?
Ibamba iqhaza kokuthi:

• I-Aldol condensation

• Ukwakhiwa kwesisekelo se-Schiff (ene-amines)

• I-Etherification (methylation → vanillin)

• I-Esterification (nge-phenolic OH)

• Ukwehliswa kwe-p-hydroxybenzyl alcohol

• I-oxidation ibe i-p-hydroxybenzoic acid

I-Q8: Ingabe le nhlanganisela ifakwe ohlwini lwezinto ezinkulu zokulawula?
Yebo. I-p-Hydroxybenzaldehyde (CAS 123-08-0) ibhaliswe ngaphansi kwe-TSCA (USA), EINECS (EU), ECL (Korea), IECSC (China), kanye nezinye izikhungo zamakhemikhali zesifunda. Akuyona into ekhawulelwe ngaphansi kokusetshenziswa kwezimboni okuvamile.

Q9: Ingabe unikeza amasampula mahhala?
I-Aozunchem inikeza amasampula amancane amahhala (10–20 g) ngezinjongo ze-R&D ezifanelekile. Inqubomgomo yesampula idinga incazelo emfushane yohlelo lokusebenza. Izindleko zokuthumela zingasebenza. Xhumana nathi ukuze ucele isampula.

Q10: Iyiphi iphrofayili yokungcola ejwayelekile yomkhiqizo wakho?
Ibanga lethu elijwayelekile liqukethe ≤0.5% isamba sezinto ezihlobene (ikakhulukazi i-o-hydroxybenzaldehyde, m-hydroxybenzaldehyde, ne-p-hydroxybenzoic acid). Ibanga lokuhlanzeka okuphezulu linokungcola komuntu ngamunye okungu-≤0.1%.

Xhumana nathi

Mayelana namanani entengo, amashidi edatha yobuchwepheshe (i-TDS/MSDS), izicelo zesampula, noma ukuxoxa ngokuhlanganisa ngokwezifiso nokunikezwa kwenqwaba, sicela uxhumane:
