Quod usus:Hoc magni momenti est quia medium quod organicum uber denique chemical compositionem, cum in usu wide pharmaceutical, aromatizer, pesticide, et batus æqualia electroplating crystal industries. In pharmaceutical industria, potest non synthesize ad intermedia sulfonamides ut ex lato spectro sterilitate synergist TMP, ampicillin et semi-penicillin summatim perstringitur (oris), tum in medium d - (-) - p-hydroxy phenyl picramate. Aromatizer in industria, est enim maxime in amet ketone, yl vanillin, ethyl vanillin, anisic aldehyde et nitrile aromatizer. In pesticide industriam, illud est maxime solebat synthesize novum genus Culex pipiens-, herbicide, et O-bromobenzonitrile hydroxyl casoron. In electroplating industriam, illud potest esse in type cyanogens-novi-liberum electroplating brightener.

1.There multa processibus, sunt praefinire ad deductiones exhibendas hydroxybenzaldehyde, p. Hoc tempore, in industriae productio maxime includit phenol, cresol, p, p, nitrotoluene et alia materia cruda.

2. Chr phenol methodus dividi Tiemann reactio gattermann reactio phenol Trichloroacetaldehyde itinere phenol glyoxylic acidum iter itineris Phenol Formaldehyde etc. Fenol processus talis aditus ad materias vestibulum processus simplex, humilis cedat atque pretium.
Processus autem p, p, ad producendum nitrotoluene hydroxybenzaldehyde includit tres gradus: oxidatio-reductionem, et hydrolysis diazotization.

Calcium-oxidatio 3.P cresol est processus directe ad oxidize cresol p, p, vel hydroxybenzaldehyde oxygeni in aere, in catalyst est actio.

Speciei processus, sequitur quod sit fluxus: addendi, p cresol, sodium hydroxide methanolum et immaculatam ferro pressura in universo vase, quam suscitare ut dissolvi omnino, cobalt addendi acetate signare reactor, caliditatem ad LV ℃ satus et oxygeni ad introducendam, ut de pressura in in vas unum, et reflecti est 1.5MPa 8-10h, stricte moderari oxygeni fluxus reactionem rate in processus et coil install refrigerationem systema in navi cum temperatus resurget et in iaccam paravi vas aqua frigida coniuncta. Tunc coepit spiram circa umorem proprie summa potestate oxygeni circiter LX ahenum serva calidissimum℃. Fine motus, materia prima in autoclave, et consumatur REDIVIVUS methanol solutarum et salsura additur de hydrochloric acidum aquae additur. In solidum, materia enim liquor percolantur per centrifuge et exaruit solidum adeptus est in vacuo, fere LX oven℃ quia 3-5h ergo, p hydroxybenzaldehyde contentus cum XCVIII% plus habere potest.
