Sulfure ndi chinthu chosafunikira ndi chiwonetsero cha ma atomiki a 16. Zowonjezera za sulfur ndi insulle m'madzi, kusungunuka pang'ono mu ethanol, ndikusungunuka mosavuta mu katebero ka mpweya2.
1.Chical katundu
- Sulfure nthawi zambiri imakhala yotumbula yachikasu, yopanda fungo komanso yopanda pake.
- Sulufule ali ndi malo ambiri, omwe onse amapangidwa ndi s8mamolekyulu a cyclic. Anthu omwe ali odziwika kwambiri ndi Orthorthombic (omwe amadziwikanso kuti rhombic sulfur, α-sulufule) ndi monoclinic sulfur (omwe amadziwikanso kuti β-sulufule).
- Orthorhombic sulfur ndi mtundu wa sulfure, ndipo potentha kwa pafupifupi 100 ° C, imatha kukhazikika kuti ipeze suluclinic sulfur. Kutentha kwa Orthorhombic sulfur ndi monoclinic sulfur ndi 95,6 ° C.Orhombic sulfur ndiye mawonekedwe a sulfure firiji. Mawonekedwe ake oyera ndi obiriwira (sulufule omwe amagulitsidwa pamsika amawoneka kuti ali ndi chikasu chochuluka kwambiri pakutsata kuchuluka kwa cycloheptalfi). Orthorhombic sulfur ndi okakamira m'madzi, ali ndi mawonekedwe osawoneka bwino, ndi malo abwino.
- Monoclinic sulfure ndi makristali osafunikira omwe adatsala atasungunulira sulufule ndikuthira madzi owonjezera. Monoclinic sulfure orthorhombic sulfur ndi mitundu ya sulfure yoyambirira kutentha kosiyanasiyana. Monoclinic sulfure ndi wokhazikika pamwamba pa 95.6 ℃, ndi kutentha, kumasintha pang'onopang'ono kukhala Orthorhombic sulfur. Malo osungunuka a Orthorhombic sulfur ndi 112.8 ℃, malo osungunuka a monoclinic sulfur ndi 119 ℃. Onsewa amasungunuka kwambiri mu CS2.
- Palinso Elastic sulfure. Elastic sulufur ndi soka wachikasu, wonyezimira zomwe sizimasungunuka mu kaboni kuposa sululu kuposa sulufule wina. Ili ndi insuluble m'madzi ndikusungunuka pang'ono. Ngati sulfur wosungunuka amathiridwa mwachangu m'madzi ozizira, sulufule wautali wakhazikika, wotambasulira sulufur. Komabe, lidzaumitsa nthawi ndikukhala monoclinic sululfure.
2. katundu wa 2.chemical
- Sulufule imatha kuwotcha mlengalenga, kujambulitsa ndi mpweya wabwino kuti apange sulufur dioxide (choncho₂) mpweya.
- Sulufule amakumana ndi zotupa zonse zotenthetsera. Amayaka mwa fluorine kuti apange sulfur Hexfuride. Mafuta a Sulfur ndi chlorine kuti apange phokoso lamphamvu kwambiri dichloride (s2Cl2). Osakaniza ofanana okhala ndi sulfur dichloride (scl) amatha kupangika pomwe chlorine ali ochulukirapo komanso othandizira, monga fecl3kapena sni4,amagwiritsidwa ntchito.
- Sulfur amatha kuchitira ndi potaziyamu hydroxide (koh) yankho la potaziyamu sulfide ndi potaziyamu latasulpate.
- Sulufule sakutengera ndi madzi komanso osakhala ma oxidi azikisi. Sulfur amakumana ndi Nitric acid ndi sulfuric acid ndipo amatha kukhala oxidizere mu sulufuric acid ndi sulufule dioxide.

- Kugwiritsa Ntchito Mafakitale
Kugwiritsa ntchito kwakukulu kwa sulfure ndikupanga ma sulufur ambiri monga sulfuric acid, sulfic, peisborosurfonation phosphoros, ndi chitsulo. Zoposa 80% ya kugwiritsa ntchito sulfar yapachaka imagwiritsidwa ntchito popanga sulufuric acid. Sulufule kwambiri yomwe imagwiritsidwa ntchito kwambiri popanga mphira wotetezeka. Ikasaka rabara yaiwisi imasiyidwa mu mphira wamba, zimapeza kutalika kwambiri, kukhazikika kwa kutentha kwamphamvu, komanso kusandulika mu organic sol. Zinthu zambiri za mphira zimapangidwa ndi mphira zowonongeka, zomwe zimapangidwa ndi mphira zojambulidwa ndi mphira ndi mafinya pa kutentha ndi zovuta zina. Sulfure amafunikiranso pakupanga ufa wakuda ndi machesi, ndipo ndi imodzi mwazipepala yazithunzi yochitira moto. Kuphatikiza apo, sulufa imatha kugwiritsidwa ntchito popanga utoto ndi utoto wa sulufurized. Mwachitsanzo, kuwerengera msanganizo wa Kaolin, kaboni, sulufule, diatomeom nthaka, kapena quartz ufa kutulutsa utoto wamtambo wotchedwa akupanga. Makampani opanga magazi ndi mankhwala amafanso gawo la mankhwala nawonso amadya solufule.
- Kugwiritsa Ntchito Zachipatala
Sulufu ndi imodzi mwazinthu zomwe zimapangidwa m'mankhwala ambiri akhungu. Mwachitsanzo, mafuta a tung amatenthedwa ndi sulufule ku sulfonate wokhala ndi sulfure asidi acid kenako osalowerera ndi madzi ammonia kuti apeze mafuta a tung. Mafuta 10% opangidwa kuchokera ku zimakhala ndi odana ndi kutupa komanso kuwonongeka koopsa ndipo amatha kugwiritsidwa ntchito pochiza zotupa za khungu ndi kutupa.
