Density: Yawan dangi yana da kusan 1.07 (ruwa = 1), wanda ke nufin yana da nauyi fiye da ruwa kuma lokacin ajiya da amfani, zai kasance a cikin ƙananan Layer idan an haɗa shi da ruwa.
Solubility: dan kadan mai narkewa a cikin ruwa, amma miscible tare da mafi yawan kwayoyin kaushi kamar ethanol, ether, acetone, da dai sauransu, wanda ya sa shi yadu shiga cikin dauki daban-daban sauran ƙarfi tsarin a Organic kira halayen.
Abubuwan sinadarai:
Reactivity na ƙungiyar aiki: Ƙungiyar sulfhydryl (-SH) a cikin kwayar halitta tana da ƙarfin amsawa kuma shine wurin aiki na yawancin halayen sinadaran. Yana iya jurewa yanayin zafi tare da mahaɗan carbonyl kamar aldehydes da ketones don samar da mahadi na thioether; Hakanan za'a iya jujjuya halayen musanya tare da halogenated hydrocarbons don samar da sabbin abubuwan haɗin carbon-sulfur, waɗanda za'a iya amfani da su don gina hadadden tsarin kwayoyin halitta.
Ƙarfafawa: Yana da ingantacciyar kwanciyar hankali a yanayin zafin jiki da matsa lamba, amma a ƙarƙashin yanayin haske, babban zafin jiki ko kasancewar oxidants mai ƙarfi, ƙungiyoyin sulfhydryl na iya zama oxidized, haifar da canje-canje a cikin abubuwan sinadarai na mahadi, don haka suna buƙatar. a adana kuma a yi amfani da shi a ƙarƙashin yanayin da ya dace, kuma ana ba da shawarar gabaɗaya a adana a cikin sanyi, iska mai duhu da duhu, da kuma guje wa haɗuwa da masu ƙarfi mai ƙarfi.
Hanyar Magana:
Yawancin lokaci ana shirya shi ta hanyar esterification na 3-mercaptopropionic acid tare da ethanol a gaban mai kara kuzari na acidic kamar sulfuric acid. A lokacin amsawa, da farko dai, ƙungiyar carboxyl da ƙungiyar hydroxyl na ethanol suna fuskantar wani canji na nucleophilic a ƙarƙashin yanayin acidic don samar da ester bond, kuma a lokaci guda ana samar da ruwa. A ƙarshen abin da ya faru, samfurin yana buƙatar tsarkakewa ta hanyar jerin matakan aiwatarwa kamar su tsaka-tsaki, wanke ruwa, da distillation don samun ingantaccen Ethyl 3-Mercaptopropionate.
Amfani:
Filin kamshi: Yana da wari na musamman kuma ana amfani da shi azaman tsaka-tsaki a cikin kayan kamshi na roba a cikin masana'antar ƙamshi, wanda zai iya ƙara ɗanɗano na musamman da kuma daidaitawa ga haɗaɗɗen ɗanɗano, kuma galibi ana amfani dashi don haɗa ɗanɗano kamar 'ya'yan itace da nama don biyan buƙatu. na abinci, kayan kwalliya da sauran masana'antu don sarrafa ƙamshi.
Filin Magunguna: Ana iya amfani da shi azaman ɗanyen abu ko tsaka-tsaki a cikin haɗin magunguna don gina sifofin ƙwayoyin cuta tare da takamaiman ayyukan ilimin halitta. Misali, a cikin hadaddun wasu magungunan da ke dauke da sulfur, ana iya shigar da kungiyoyin sulfhydryl a cikin kwayoyin da aka yi niyya ta hanyar halayen sinadarai, ta haka ne ke ba da takamaiman ayyukan harhada magunguna ga miyagun ƙwayoyi, kamar antioxidant, antimicrobial, ko daidaita ayyukan enzyme.
Noma: Har ila yau, yana da wani aikace-aikacen da ake amfani da shi wajen hada magungunan kashe qwari, ta hanyar gyara tsarinsa na kwayoyin halitta da kuma gabatar da wasu kungiyoyi masu aiki, ta yadda zai iya nuna tasiri mai kyau ga kwari ko cututtuka a kan amfanin gona, wanda ke taimakawa wajen inganta yawan amfanin gona da ingancin amfanin gona. da kuma tabbatar da zaman lafiyar noma.
