N-Valeraldehyde

Zouping Jinxing Chemical Co., Ltd. yog ib qho ntawm cov ua lag luam thiab cov muag khoom ntawm n-valeraldehyde hauv Suav teb. Yog tias koj yuav mus rau cov lag luam wholesale bulk n-valeraldehyde ua nyob rau hauv Suav teb, txais tos kom tau txais cov qauv dawb los ntawm peb lub hoobkas. Tag nrho cov khoom customized yog nrog cov khoom zoo thiab tus nqi qis.

Cov tsos mob: tsis muaj xim, pob tshab kua nrog lub zog, pungent, acrid tsw; nthuav tawm nutty / almond sau ntawv raws li qhov siab dilution (qhov no yog tus yam ntxwv aroma profile ntawm tsawg concentrations siv nyob rau hauv cov zaub mov flavoring).
Kub taw tes: kwv yees li . 103℃(760 mmHg)
Melting point: Approx. -91 degree
Ceev: 0.809-0.811 g / cm³ (20 degree)
Flash point: Kwv yees li . 12℃(kaw khob) → Cov kua nplaum nplaum heev (GHS Qeb 2), UN 2058 PG II
Refractive Index: n²⁰D ≈ 1.394–1.396
Solubility: me ntsis soluble hauv dej (kwv yees . 1.6 g / 100 mL ntawm 20 degree); miscible nrog ethanol, diethyl ether, acetone, benzene, thiab chloroform; nkag oxidizes rau valeric acid.
Kev ruaj ntseg: Oxygen-sensitive; undergoes autoxidation los tsim peroxides thaum lub sij hawm cia (peroxide tus nqi yuav tsum tau kuaj ua ntej distillation!); Nws yooj yim rau polymerization thaum raug lub teeb.

Pawg aldehyde dictates nws reactivity:
Yooj yim oxidized → valeric acid (yuav maj mam oxidized los ntawm nitric acid, KMnO₄, los yog txawm atmospheric O₂)
Yooj yim txo → n-pentanol (ntawm NaBH₄ lossis catalytic hydrogenation)
Aldol condensation → tus kheej - los yog cross-condensation yields , -unsaturated aldehydes (piv txwv li, 2-pentenal)
Cov tshuaj tiv thaiv nrog amines / cawv → imines, acetals (kev tsim acetal feem ntau yog siv los tiv thaiv pawg aldehyde hauv acidic alcoholic media)

Fragrances thiab flavours: Siv rau hauv cov lej rau cov txiv ntoo, kas fes, thiab nqaij flavorings; nws cov derivative, valeraldehyde diethyl acetal, muaj ib qho profile me me thiab feem ntau siv los ua cov tshuaj tsw qab hauv cov khoom tu tus kheej.
Organic synthesis intermediate: Siv nyob rau hauv zus tau tej cov n-amyl cawv, valeric acid, -pentenal, roj hmab accelerators, thiab tshuaj sab chains (xws li, precursors rau tej barbiturates).
Agrochemicals/Fine chemicals: Siv rau synthesizing side chains of uniconazole-type fungicides and intermediates for pyrethroids.
Cov qauv ntsuas: Siv rau GC / MS tuav ntsuas ntsuas ntsuas thiab kev tshawb fawb ntawm cov ntxhiab tsw ntawm aldehydes.

GHS: H225 Cov nplaim hluav taws kub heev; H302 Ua phem yog tias nqos; H315 / H318 / H335 Ua rau tawv nqaij / qhov muag khaus thiab ua pa ua pa; Ntev ntev ua rau cov tshuaj loog.
Vapors irritate mucous daim nyias nyias; high concentrations ua rau mob taub hau thiab xeev siab; kua ua rau mob hnyav thaum tiv nrog qhov muag.
Kev tuav: Siv fume hood; tawg- cov khoom pov thawj; hnav hnab looj tes nitrile thiab looj tsom iav dub; tsis txhob cia nrog cov oxidizers muaj zog, muaj zog hauv paus, lossis amines (kev pheej hmoo ntawm exothermic disproportionation / polymerization).
Cia / Thauj: Daim pam nrog nitrogen los yog ntim puv ntim; khaws cia deb ntawm lub teeb; khaws cia tsawg dua lossis sib npaug li 25 degree; kom deb ntawm qhov hluav taws kub; saib xyuas cov qib peroxide tsis tu ncua; tsis txhob distilled rau dryness.
Kev tua hluav taws: Cawv-ua npuas dej, CO₂, tshuaj qhuav, xuab zeb / av; tsis txhob siv lub dav hlau dej ncaj qha (qhov chaw qis qis ua rau muaj kev pheej hmoo ntawm rov- ignition).
