Chotsani zomwe DBU yakhala ikugwiritsidwa ntchito m'njira zosiyanasiyana zochotsera kuti mamolekyulu a reagent akhazikitse zomangira zopanda unsaturated., monga zapakatikati ndi zopangira za organic synthesis, ndipo zitsanzo zochepa ndizokwanira kuwona kugwiritsa ntchito DBU mu ...

1. Kugwiritsa ntchito mankhwala opangira tsitsi Chofunikira cha diamine ndikuti homopolymer kapena copolymer yake sisungunuka m'madzi., koma zili "kupuma kwamadzi", Kuchuluka kwa Madzi Kufikira 20% ku 30% zolemera zake, ndi pamene ambient...

1. Amagwiritsidwa ntchito ngati chizindikiro cha acid-base komanso chizindikiro chodziwira kuchuluka kwa asidi wamafuta Phenolphthalein ali ndi chidwi chosintha mitundu.. Pansi pa asidi-pafupi ndi ndale (pH0-8.2), mamolekyu a phenolphthalein samalekanitsa ndipo alibe mtundu. Mu ...

Trimethyl Orthoacetate, Amadziwikanso monga trimethoxythanene, ndi EST yoyambirira ya acid, mawonekedwe a molecular (C5H12o3) imagwiritsidwa ntchito makamaka yamankhwala, mankhwala ophera tizilombo, zonunkhira ndi kaphatikizidwe zina. Njira wamba njira ndi njira ya Acetunile, zomwe zimagwiritsa ntchito...

Dichloroacetyl chloride ndi gawo lapakati pakupanga mankhwala ophera tizirombo ndi herbicides., ndipo imagwiritsidwanso ntchito kwambiri m'munda wa Aaxiliaries ndi synthesical synthesis. Njira zazikulu zopangira ndi dichloroacetate acyl chloride ndi...

Ndi ukatswiri waluso kwambiri pamtunda wonse wamakampani amtengo wapatali, China imapereka mitundu yonse yothira mankhwala ofunikira padziko lonse lapansi. Kwa opanga ndi othandizira kudutsa magawo ambiri, Kupeza mankhwala ofunikira ngati phenolphthalein, Ethenyl Acetate,...

Mankhwala opanga mankhwala amatenga gawo lofunikira m'minda ya sayansi ndi mafakitale. Mu blog positi, Tiona mitundu itatu yapadera: Phenolphthalein, Ethenyl Acetate wopangidwa ndi China Ethenyl Acetate supplier, ndi chlorobnzene. Ma compound awa ali ndi zosiyana...

Monga wopanga mankhwala padziko lonse lapansi, China imapanga zopangira zazikulu ndi zotumphukira zofunika kwambiri pamaketani apadziko lonse lapansi. Ngakhale mikangano ya geopolitical, China lalikulu kupanga mphamvu, ogwira ntchito aluso, ndi robust logistics infrastructure imayiyika ngati ...

Mankhwala opangidwa ndi mankhwala amagwira ntchito yofunika kwambiri m'mafakitale osiyanasiyana, kuyambira pharmaceuticals mpaka kupanga. Mu chitsogozo chokwanira ichi, Tidzafumudwa, Mapulogalamu, ndi tanthauzo la zinthu zitatu zofunika: Prow-1-the, Ethylene glycol,...

Organic chemistry imathandizira ma reagents ogwirizana kuti ayendetse zofunikira, kuchokera ku mankhwala kupita ku zaulimi. Sodium methoxide, ethyltriphenylphosphonium bromide ndi cyclohexanone amawonetsa mamolekyu atatu omwe amapititsa patsogolo kusinthasintha kwa ma labotale..
