Dimethyl Etera - Contemporary wahie no ka kakolina diesel kiko'ī

Nā mea kemika o - nā mea loaʻa o ka waiʻona mai ke kino, na nā lātoma o a he hydrogen'Ātoma o ka OH pae ua hookomoia ma luna o kekahi o carbon'ano'ē. No ka typical ester metamerism a isomerism hydrocarbon kaulahao.

hydrocarbon kaula isomerism mea ku pono i kona ai manamana ai.

Metamerism -ʻano o ka isomerism ma i elua a oi nā mea kemika i ka like hakakino haʻilula akā,ʻano hakakino 'ole ma muli o ai i kaʻokoʻa radicals ma na aoao a elua o ka oxygen ma "alahaka". No ka laʻana, ka mea hakakino haʻilula hoʻopili like i ekolu S4N10O ester:

- CH3-O-Ch (CH3) 2;

- CH3-O-C3H7;

- C2H5-O-C2H5.

e hoomakaukau mau waiwai synthetically, me dimethyl Etera wale no. Ke haʻilula o keia hui ua poe e mau meto radicals, i mea interconnected oxygen ma "alahaka".

It E e hoʻomaopopo i ke 'ano o nā nā mea kemika i loko o ka noa ana, aole ia i kānāwai. Dimethyl a me ka meto'eto nā mea kemika, - kinoea. O kekahi mau Poeikohoia - wai, oiai na nā mea kemika kiʻekiʻe - puaʻa hiwa. Ka mea, ua nui loa poorly wailana i loko o ka wai, ua ike pono no i loko o ke aloha nā'uheheʻe. Ka 'elele (dipropyl, propiletilovy diethyl) - ka nui ke aloha nā'uheheʻe. Helu waiwai o kēia mau ke aloha i huiʻia oko ma ka hakakino kaumaha.

Dimethyl Etera wale no e hoomakaukau ai no

Wehewehe i ka waiwai o ka haiia wailana i loko o ka wai, ethanol, diethyl a me ka dipropyl Etera wale no. Kēia ester ua loaa ia ma muli o ka dehydration a me ka metanola like me ka he hopena ia o ka? Iecaianoaaiiie o metanola mai CO a me h2. Hoʻohana 'ia ma ka refrigeration nenoai like me ka refrigerant.

I ke kokoke wā e hiki mai, kakolina diesel kiko'ī e e hoololiia ole ma ke kinoea, a me ka dimethyl Etera wale no. Oia ka? Aeiino? Oeoey o ko lākou waiwai e lilo aku, he nui ho'ēmi hoohalikeia me ka hoʻololi i kūlohelohe kinoea. Ke alakai'āina i loko o ka? Iecaianoaaiiie o kēia mau kiko'ī i ka US, Rusia a me Japan.

I ke kakahiaka nui 21st kenekulia, ka Lūkini aupuni nō ma luna o ka hoʻohana 'ana o kekahi papa hana mōʻalihaku ma alanui amo. Dimethyl Etera ua hoʻohana 'ia i loko o ia i kona kalaka. Oia ka'ano'ē hoʻoholo i i aie i ka mea i nā ea puka o ka naikokene i huiʻia mai kakolina diesel kiko'ī hoʻouka kekahi ma ia i kona kalaka, i loko o ka hoʻokumu Oeao kekahi mau manawa. Dimethyl Etera mea maikaʻi no kēia 'ano o ka engine, ka mea, aneane e ole pono e e? Aeiino?. Wale nō ma o ka hoʻohana 'ana i kekahi papa hana hou wahie hou hōʻano hou engine i ka nui o Euro-3? Aneeo.

Aupuni a puni ke ao nei Ua ikaika i ka wā e hiki mai wahie no ka kakolina diesel kiko'ī mea dimethyl Etera wale no. I kēia lā ia mea he waiwai huaʻano nui ma ka hoohehee maemae au ia maoli kinoea. Ma nā kuʻina mua o ke kaʻina lends ia iho, e hoʻoponoʻia maoli kinoea, ma laila ka hana i ka hoʻololi kemikala kinoea. Mahope, ka mea, ua hoohuliia mai i loko o meto ka waiʻona. E möakäka hou amenable metanola dehydration, malaila loaa dimethyl Etera wale no. Aia o kekahi papa hana no ka hoʻololi kemikala o mai la ester - kauoha huli ana o ka hoʻololi kemikala kinoea i ka metanola.

Nā mea kemika hoʻohālike au i ka kakolina diesel wahie i kona pono, a, o ka papa, keakea. Ma ka 'ole o ka ester nā lātoma nalowale "kalapona-kalapona" hoopaa. Aie i ka mea nui o oxygen maʻiʻo ka mea, ua hoakaka maikai atomization ma ka injecting ea i loko o ka 'ia me ka wela ole kiekie ae baila aʻela i ka waiwai nona iho. Kēia mau 'ano hoʻoikaika' ana'ā. Ma ka hana o keia koho wahie emi engine kani, ka mea maoli kona pono.

I ka papa kuhikuhiE keakea o keia ester nā haʻahaʻa calorific waiwai, a me ka lalo nuʻa. A pau i kēia hiki aku ai i ka mahuahua ma ka wahie hokii. Keia mea, uaʻilihune ia loa lubricating waiwai.
