Ensonga enkulu ezifuga mu kukola Bisphenol A
Mu nsonga y’obulongoofu bw’ebintu ebisookerwako, phenol ne acetone, ng’ebintu ebikulu ebisookerwako mu kukola bisphenol A, byetaaga okufuga ennyo obulongoofu bwabyo. Obulongoofu bwa phenol tebulina kuba wansi wa 99.5%, ate obulongoofu bwa acetone bulina okutuuka ku bitundu ebisukka mu 99%. Ebintu ebisookerwako eby’obulongoofu obw’amaanyi bisobola okukendeeza ku kutaataaganyizibwa kw’obucaafu ku nsengekera n’okukakasa nti ensengekera egenda bulungi.
Okufuga ebbugumu ly’ensengekera (reaction temperature) kikulu nnyo. Ebbugumu ly’ensengekera y’okufuumuuka okutwalira awamu liba wakati wa 40 – 60°C. Mu bbugumu lino, omutindo gw’ensengekera n’okulonda kw’ebintu bisobola okutuuka ku bbalansi ennungi. Ebbugumu erisukkiridde oba eri wansi ennyo lijja kukosa amakungula n’omutindo gwa bisphenol A BPA. Enkola n’okulonda kw’ekirungo ekiziyiza (catalyst) bye bisalawo obulagirizi bw’ensengekera. Ebirungo ebikola asidi ebitera okukozesebwa nga asidi wa salufuriki byetaaga okuteekebwa mu nkola okutuufu kw’obungi bwabyo n’obungi bwabyo. Okutwalira awamu, obungi bwa asidi wa salufaali bukyukakyuka mu bbanga erigere, era ddoozi kitundu kigere ku bungi bw’ebintu ebisookerwako byonna, okusobola okukakasa nti ekirungo ekiziyiza okuzimba kikola omulimu gwakyo ogusinga obulungi. Puleesa y’okuddamu nayo ekosa okukola kwa bisphenol A BPA. Ekipimo kya puleesa ekituufu kiri 0.5 – 1.5 MPa. Embeera ya puleesa ennywevu eyamba okukuuma obutebenkevu bw’ensengekera y’ensengekera era etumbula okutambuza kw’amasasi n’okukulaakulana kw’ensengekera. Omugerageranyo gw’ebintu gukwatagana butereevu n’obulungi bw’ensengekera. Omugerageranyo gwa molar ogwa phenol ne acetone gutera okufugibwa ku 2.5 – 3.5:1. Omugerageranyo omutuufu gusobola okufuula ebigimusa okukola mu bujjuvu, okwongera ku makungula ga bisphenol A BPA, n’okukendeeza ku bivaamu.

Bisphenol A BPA modification eyongera ku maanyi g’ebyuma, okuziyiza okukunya n’okwambala, nga yeetegefu okukola ku kusoomoozebwa okusaba.

Bw’oba ​​oyagala okugula ebintu eby’eddagala ebyesigika, nsaba onoonye kkampuni ya Shandong Pulisi Chemical Co., Ltd., essira erisinga kulissa ku “ddagala ery’omutindo” era emaze emyaka 20 ng’ekola.
