Nhanganyaya

Sudan yellow is an organic compound ine zita remakemikari zita rekuti Sudan I. Inotevera nhanganyaya yezvakasikwa, mashandisirwo, nzira dzekugadzirira uye ruzivo rwekuchengetedzwa kweSudan Yellow:

Hunhu:

Sudan yero iorenji-yero kusvika kune yakatsvuka-brown crystalline poda ine special sitirobheri inonaka. Inonyungudika mu ethanol, methylene chloride uye phenol uye isinganyunguriki mumvura. Sudan yero inogadzikana kuchiedza nekupisa, asi inoora zviri nyore pasi pemamiriro e alkaline.

Zvishandiso: Inogona zvakare kushandiswa muindasitiri yedhayi nependi, pamwe nemavara emaikorosikopu mukuedza kwebhayoloji.

Nzira:

Sudan yero inogona kugadzirwa nekuita kwemamines anonhuhwirira akadai seaniline uye benzidine ine aniline methyl ketone. Mukuita, inonhuhwirira amine uye aniline methyl ketone inopinda amine exchange reaction pamberi pe sodium hydroxide kuti igadzire Sudan yero.

Ruzivo Rwekuchengetedza: Kutora kwenguva refu kana kuwandisa kweSudan yero kunogona kuunza njodzi dzehutano kuvanhu. Iko kushandiswa kweSudan yero kunoda kudzora kwakasimba kwedosi uye kutevedzera zvinoenderana nemitemo uye zviyero. Pamusoro pezvo, yeSudan yero inofanirwawo kudzivirira kusangana neganda kana inhalation yeguruva rayo, izvo zvinogona kukonzera allergic reaction kana kutsamwa kwekufema.
