Menene amfanin masana'antu na cyanide?

Cyanide, wani sinadari mai dauke da rukunin cyano mai Carbon atom uku - wanda aka haɗa shi da atom na nitrogen, sananne ne saboda yawan gubarsa. Duk da haka, yana kuma taka muhimmiyar rawa a fannoni daban-daban saboda keɓantattun halayensa na sinadarai.

1. Masana'antu

Ɗaya daga cikin muhimman aikace-aikacen Cyanide shine a masana'antar haƙar ma'adinai , musamman a fannin haƙar ma'adinai masu daraja kamar zinariya da azurfa. Ana kiran wannan tsari cyanidation ko tsarin cyanide.

Zinc yana kawar da zinariya ko azurfa daga hadadden ion a cikin maganin, yana ba da damar dawo da karafa masu daraja.

2. Masana'antar Sinadarin

Haɗin Cyanide sune tsaka-tsaki masu mahimmanci a cikin samar da nau'ikan sinadarai masu yawa.

Robobi

• Ana amfani da abubuwan da ake amfani da su na Cyanide wajen samar da roba da robobi. Alal misali, acrylonitrile, wanda ya ƙunshi ƙungiyar cyano, shine maɓalli mai mahimmanci a cikin samar da polyacrylonitrile (PAN). Ana amfani da PAN don yin zaren acrylic, waɗanda ake amfani da su a masana'antar yadi don yin tufafi, kafet, da kayan kwalliya. Ta hanyar tsari na polymerization, ƙwayoyin acrylonitrile suna haɗuwa tare don samar da dogayen sarƙoƙi na polyacrylonitrile.

Haske

• Ana hada wasu rini na yadi ta amfani da sinadarai na tushen cyanide. Za a iya amfani da Cyanide-wanda ke dauke da mahadi don gabatar da ƙungiyoyi masu aiki a cikin kwayoyin rini, wanda zai iya rinjayar launi, solubility, da kayan aiki na sauri. Misali, wasu rini masu amsawa waɗanda zasu iya samar da haɗin gwiwa tare da filayen yadi yayin rini na iya ƙunsar ƙungiyoyin aikin cyanide waɗanda aka samo, suna ba da gudummawa ga ikon rini na rini da canza launin masana'anta yadda ya kamata.

Pharmaceuticals

• Cyanide yana taka rawa wajen kera magunguna da kayan aikin magunguna masu aiki (APIs). Duk da cewa ana kayyade amfani da siyanide a cikin magunguna sosai saboda yawan gubarsa, yana iya shiga cikin halayen sinadarai yayin da ake hada hadadden kwayoyin halitta. Misali, a cikin wasu hanyoyin haɗin gwal-mataki na magunguna, ana iya amfani da cyanide don gabatar da ƙungiyar cyano a cikin kwayoyin halitta. Wannan rukunin cyano za a iya ƙara inganta shi ta hanyar matakai kamar hydrolysis don samar da acid carboxylic, ko raguwa don samar da amines, waɗanda suke da mahimmancin ƙungiyoyi masu aiki a cikin magunguna da yawa.

3. Electroplating da Metal Jiyya

Cyanide mafita ana amfani da ko'ina a electroplating matakai.

Kayayyakin kayan ado

• A cikin samar da kayan ado masu inganci, cyanide - tushen electroplating mafita ana amfani da su saka karafa kamar zinariya, azurfa, da jan karfe a saman. Cyanide yana aiki a matsayin wakili mai rikitarwa, wanda ke taimakawa wajen samun suturar ƙarfe mai santsi, uniform, da mannewa. Alal misali, a cikin wutar lantarki na zinariya, zinari - hadaddun cyanide a cikin bayani yana ba da damar mafi kyawun sarrafa adadin ajiya da ingancin launi na zinariya a kan kayan ado na kayan ado. A lokacin electroplating, zinariya - cyanide hadaddun dissociates a cathode, da kuma zinariya ions an rage su samar da wani bakin ciki, ko da Layer na zinariya a saman kayan ado.

Electronics

• A cikin masana'antar lantarki, ana amfani da sinadarai na tushen electroplating don ɗaukar abubuwan da aka gyara. Wannan yana inganta haɓaka aiki da juriya na lalata sassan lantarki. Misali, jan karfe - cyanide electroplating ana amfani da shi don saka wani bakin ciki na jan karfe akan allon da'ira (PCBs). Tushen jan ƙarfe yana ba da ingantaccen ƙarfin lantarki, kuma amfani da cyanide a cikin wanka na lantarki yana taimakawa wajen samun uniform da lahani - murfin jan ƙarfe na kyauta, wanda ke da mahimmanci don ingantaccen aiki na PCB.

4. Sauran Aikace-aikacen Masana'antu

Karfe Quenching

• Ana iya amfani da mahadi na Cyanide a cikin maganin zafi na karafa, musamman a cikin wani tsari da ake kira cyanide. A cikin cyaniding, sassan karfe suna zafi a cikin wanka mai dauke da gishiri na cyanide. Wannan tsari yana gabatar da carbon da nitrogen a cikin saman karfe, yana ƙarfafa shi. Yayin da cyanide ke rubewa a yanayin zafi mai zafi, carbon da nitrogen atoms suna yaduwa cikin saman karfe, suna samar da sinadarai masu tauri irin su nitrides iron da carbides. Wadannan mahadi suna haɓaka lalacewa da juriya na ƙarfin ƙarfe, suna sa ya zama mai ɗorewa don aikace-aikace daban-daban.

Tsarin Halitta

• Ana amfani da Cyanide don shigar da ƙungiyar cyano (\(-CN\)) zuwa ƙwayoyin halitta, suna samar da cyanides na halitta (nitriles). Waɗannan nitriles za a iya ƙara canza su zuwa wasu ƙungiyoyi masu aiki. Misali, hydrolysis na nitrile a gaban acid ko tushe na iya samar da carboxylic acid. Rage nitrile na iya haifar da samuwar amine. Wannan ya sa cyanide ya zama tubalin gini mai mahimmanci wajen haɗa nau'ikan mahaɗan halitta iri-iri, gami da waɗanda ake amfani da su wajen samar da turare, dandano, da sauran sinadarai na musamman.

Samar da Sauran Sinadaran

• Ana amfani da Cyanide wajen samar da sinadarai irin su cyanuric chloride. Cyanuric chloride wani muhimmin tsaka-tsaki ne a cikin samar da magungunan ciyawa, magungunan kashe qwari, da rini. Ana samar da shi ta hanyar trimerization na cyanogen chloride, wanda sau da yawa ana haɗa shi daga tushen cyanide. Ta hanyar wannan canjin sinadarai, cyanide yana ba da gudummawa ga ƙirƙirar mahadi masu mahimmanci ga masana'antu daban-daban, daga aikin gona zuwa rini.

A ƙarshe, duk da yanayinsa mai guba sosai, haɓakar sinadarai na musamman na cyanide ya sa ya zama mahimmin fili a cikin hanyoyin masana'antu da yawa. Koyaya, saboda tsananin dafin sa, ana aiwatar da tsauraran matakan tsaro da ka'idojin muhalli don tabbatar da yadda ake sarrafa shi, amfani da shi, da zubar da shi cikin saitunan masana'antu.
