I le avea ai o le gaosiga faʻapolofesa, matou te fia tuʻuina atu ia te oe le maualuga o le POLYETHYLENE GLYCOL MONO-4-NONYLPHENYL ETHER CAS 26027-38-3. Ma o le a matou ofoina atu ia te oe le auaunaga sili ona lelei pe a uma ona faʻatau ma tuʻuina atu taimi.

3,5-Dibromoacetophenone CAS 14401-73-1Liquid tioata eletise oloa; Intermediate - organic intermediate

4-Formylbenzoic acid CAS 619-66-9 e le mafai ona solu i le vai, soluble i le DMF, ma e mafai ona oʻo i le esterification ma le condensation aldol i le ava malosi. O se mea taua tele i le faʻaogaina o meaola, faʻaaogaina lautele i vailaʻau, vailaʻau faʻamaʻi, faʻapipiʻi, vai tioata tioata, mea polymer ma mea manogi manogi.

Faʻafeiloaʻi e faʻatau le N-(Hydroxymethyl)phthalimide CAS 118-29-6 mai ia i matou. E mafua mai i le tali i le va o le phthalimide ma le formaldehyde. Faaopopo le formaldehyde i le ulo tali, faʻaopopo vai e faʻatupu ai le formaldehyde i se faʻatonuga e tusa ma le 12%. Togi i le phthalimide i lalo o le fa'aosoina, ma o le fua o le phthalimide: formaldehyde=1:1.1 (fuafua molar). O le vevela na siitia i le 98-102 ° C, refluxed mo le 2.5h, malulu i le 35 ° C, faʻamama faʻamamago, ma faʻagogo ina ia maua ai le oloa maeʻa.

O matou o se taʻutaʻua taʻutaʻua o Chloroacetaldehyde dimethyl acetal CAS 97-97-2 i Saina. Chloroacetaldehyde dimethyl acetal CAS 97-97-2 o loʻo maua i faʻatauga ma e mafai ona vave tuʻuina atu. COA, MSDS ma TDS o Chloroacetaldehyde dimethyl acetal CAS 97-97 -2.

Faʻafeiloaʻi oe e te sau i la matou fale gaosi oloa e faʻatau le faʻatauga lata mai, tau maualalo, ma le maualuga 4-Bromochlorobenzene CAS 106-39-8. Acicular tioata e fa'aulu mai le ava malosi. Le mea fa'afefeteina o le 68 ° C, o le mea fa'afefeteina o le 196 ° C. Soluble i le eter, benzene, chloroform ma le ava vevela, e le mafai ona fa'afefeteina i le vai, fa'atatau i le density 1.576 (71/4â), fa'asino fa'asino 1.5531 (70â) .
