Nhanganyaya

makemikari zvinhu

Mvura isina ruvara inopenya inopfuta ine asphyxiating aldehyde smell. Zvishoma soluble mumvura. Inosanganiswa ne ethanol, ether, ethyl acetate, acetone, toluene, zvakasiyana-siyana zvemamwe organic solvents nemafuta.

Shandisa

Inoshandiswa muorganic synthesis uye mbishi kugadzira zvinonhuwira

Shandisa

GB 2760-96 inotsanangura zvinodyiwa zvinotenderwa kushandiswa. Inonyanya kushandiswa kugadzira mabhanana, caramel uye zvimwe zvinonaka zvemichero.

Shandisa

butyraldehyde yakakosha yepakati. n-butanol inogona kugadzirwa nehydrogenation ye n-butanal; 2-ethylhexanol inogona kugadzirwa ne condensation dehydration uye ipapo hydrogenation, uye n-butanol uye 2-ethylhexanol ndiyo huru mbishi zvinhu zve plasticizers. n-butyric acid inogona kubudiswa ne oxidation ye n-butyric acid; trimethylolpropane inogona kubudiswa ne condensation ne formaldehyde, iyo inonzi plasticizer ye synthesis yealkyd resin uye yakasvibiswa yemafuta ekuomesa mhepo; condensation ne phenol kubudisa mafuta-soluble resin; condensation ne urea inogona kubudisa doro-soluble resin; zvigadzirwa zvakanyungudutswa nepolyvinyl doro, butylamine, thiourea, diphenylguanidine kana methyl carbamate zvinhu mbishi uye, condensation nemhando dzakasiyana siyana dzedoro inoshandiswa se solvent ye celluloid, resin, rabha uye zvigadzirwa zvemishonga; indasitiri yemishonga inoshandiswa kugadzira "Mianerton", "pyrimethamine", uye amylamide.

Shandisa

Rubber glue, rubber accelerator, synthetic resin ester, kugadzira butyric acid, nezvimwewo. Iyo hexane solution ndiyo reagent yekuona ozone. Inoshandiswa sechinhu chinonyungudutsa che lipids, chinoshandiswawo mukugadzirira maflavour uye zvinonhuwira uye sekuchengetedza.

Nzira yekugadzira

pari zvino, nzira dzekugadzira butyraldehyde dzinotora nzira dzinotevera: 1. propylene carbonyl synthesis nzira propylene uye synthesis gasi inoita carbonyl synthesis reaction muhupo hweCo kana Rh catalyst kugadzira n-butyraldehyde uye isobutyraldehyde. Nekuda kwezvakasiyana zvinokonzeresa uye maitiro emamiriro anoshandiswa, anogona kukamurwa kuita yakakwira-kudzvanywa kabhoni synthesis ine cobalt carbonyl secatalyst uye yakaderera-kudzvanywa kabhoni synthesis ine rhodium carbonyl phosphine yakaoma se catalyst. Iyo yakakwira yekumanikidza nzira ine yakakwira reaction kudzvanywa uye akawanda ne-zvigadzirwa, nekudaro kuwedzera mutengo wekugadzira. Iyo yakaderera-kudzvanywa carbonyl synthesis nzira ine yakaderera reaction pressure, yakanaka isomer ratio ye8-10: 1, zvishoma ne-zvigadzirwa, yakanyanya kutendeuka mwero, yakaderera mbishi, yakaderera mashandisiro emagetsi, midziyo yakapusa, pfupi nzira, inoratidza yakanakisa hupfumi mhedzisiro uye kukurumidza kukura. 2. Acetaldehyde condensation nzira. 3. Butanol oxidative dehydrogenation nzira inoshandisa sirivha sechinhu chinokonzera, uye butanol yakasvibiswa nemhepo mune imwe nhanho, uye zvino zvinogadzirisa zvinogadziriswa, zvinoparadzaniswa, uye zvinogadziriswa kuti zviwane chigadzirwa chakapedzwa.

Nzira yekugadzira

Inowanikwa nekuoma distillation ye calcium butyrate uye calcium formate.

Iyo mhute inowanikwa ne dehydrogenation ye catalyst.
