    Kopo

    1.E sebelisoa e le solvent bakeng sa ho hlahisa methyl-ethyl ketone peroxide, flurocontaining anticorrosive coatings.

    2.E sebelisoa e le plasticizer ea cellulose acetate, e thibelang menoang le solvent ea polyfluoroethylene coating.

    3. Ke karolo e bohareng ea rodenticide diphacin, Tetramine le chlorratone.

    Thepa

    Dimethyl phthalate ke mokelikeli o pepeneneng o se nang 'mala, o monko o monate hanyane. Ha e kopane le ethanol, ether, e qhibilihang ka har'a benzene, acetone le metsoako e meng ea tlhaho, e ke keng ea qhibiliha metsing le oli ea liminerale.

    Polokelo

    1. Boloka sebakeng sa polokelo se phodileng, se omeletseng, hole le mollo, letsatsi le pula. Qoba tšusumetso e matla nakong ea lipalangoang.

    2. Plasticizer e nang le matla a matla a ho qhibiliha. E sebelisoa e le polasetiki bakeng sa rabara ea nitrile, resin ea vinyl, filimi ea selulose ea acetate, cellophane, varnish le phofo ea molding, joalo-joalo E ka boela ea sebelisoa e le solvent bakeng sa ho lokisetsa methyl ethyl ketone peroxide. E na le thepa e babatsehang ea ho etsa lifilimi, ho khomarela le ho hanyetsa metsi, le botsitso bo phahameng ba mocheso, empa ho bonolo ho khanya ka mocheso o tlaase 'me o na le ho hloka botsitso ho phahameng. Ka hona, hangata e sebelisoa hammoho le li-plasticizers tse kang diethyl phthalate bakeng sa polasetiki ea rabara. E ka ntlafatsa polasetiki ea motsoako oa rabara ha e sebelisoa e le moemeli, haholo-holo e loketseng rabara ea nitrile le rabara ea neoprene. E ka boela ea sebelisoa e le oli e thibelang menoang le e lelekang. E na le phello e lelekang likokoanyana tse monyang mali tse kang menoang, sandflies, culms le menoang. Nako e sebetsang ea ho leleka ke lihora tse 2 ho isa ho tse 4.

    Botsitso

    1. Ha e qhibilihe metsing a mocheso oa kamore, e qhibiliha ka har'a metsoako e mengata ea lintho tse phelang le li-hydrocarbon, 'me e lumellana hantle le li-resin tse ngata tsa indasteri. Dimethyl phthalate e ka cha. Ha e tšoara mollo, sebelisa metsi, sesebelisoa sa ho tima foam, carbon dioxide, sesebelisoa sa ho tima phofo ho tima mollo.

    2. Lintho tsa lik'hemik'hale: E tsitsitse moeeng le mocheso, 'me ha e bole ha e futhumala lihora tse 50 haufi le ntlha e belang. Ha mouoane oa dimethyl phthalate o fetisoa ka sebōpi sa ho futhumatsa sa 450 ° C ka tekanyo ea 0.4g / min, ho senyeha ho fokolang feela ho etsahala. Sehlahisoa ke metsi a 4.6%, 28.2% phthalic anhydride, le 51% ea lintho tse sa nke lehlakore. Tse ling kaofela ke formaldehyde. Tlas'a maemo a tšoanang, 36% ho 608 ° C, 97% ho 805 ° C, le 100% ho 1000 ° C e na le pyrolysis.

    3. Ha dimethyl phthalate e le hydrolyzed ka tharollo ea methanol ea caustic potassium ho 30 ° C, 22.4% ka hora e le 'ngoe, 35.9% ka lihora tse 4, le 43.8% ka lihora tse 8 ke hydrolyzed.

    4. Dimethyl phthalate e sebetsana le methylmagnesium bromide ho benzene, 'me ha e futhumatsoa mocheso oa kamore kapa ka bateng ea metsi, 1,2-bis(α-hydroxyisopropyl)benzene e etsoa. E sebetsana le phenyl magnesium bromide ho hlahisa 10,10-diphenylathrone.
