Intangiriro

4-4-Hydroxy-3-mikorerexybutyl-2-imwe, izwi kandi nka 4-hydroxy-3-mikorerexypentanone, ni ifumbire mvaruganda. Ibikurikira ni intangiriro kuri bimwe mubintu byayo, ikoreshwa, uburyo bwo gukora namakuru yumutekano:

Ubwiza:

- Kugaragara: Ibara ritagira ibara cyangwa ryoroshye ry'umuhondo cyangwa bikomeye.

- Gukemura: Gushonga mumashanyarazi kama nka Ethanol na dimethylformamide, idashonga mumazi.

- Uburozi: Urusange ni uburozi kandi rusaba ingamba zumutekano zikenewe mugihe uhumeka cyangwa uhuye nuruhu.

Koresha:

- Ubushakashatsi bwa Chimie: Irashobora kandi gukoreshwa nka reagent kubushakashatsi bwa chimie.

Uburyo:

Uburyo bwo gutegura 4-4-hydroxy-3-mikorerexybutyl-2-imwe irashobora kugerwaho na synthesis organic mubihe bikwiye. Hashobora kubaho inzira nyinshi zo kubitegura, ariko dore bumwe muburyo bushoboka:

Kuramo urugero rukwiye rwa pentanone mumashanyarazi.

Ongeramo sodium hydroxide ikabije.

Ku bushyuhe burigihe nigitutu, methanol yongeweho buhoro buhoro muburyo buvanze.

Hiyongereyeho methanol, 4-4-hydroxy-3-mikorerexybutyl-2-imwe ikorwa muruvange rwa reaction.

Ibicuruzwa byongeye gutunganywa no kwezwa kugirango ubone ibice byanyuma.

Amakuru yumutekano:

- Uru ruganda rufite uburozi kandi rugomba kwirindwa guhumeka neza cyangwa guhuza uruhu.

- Hagomba gufatwa ingamba zikwiye z'umutekano mugihe zikoreshwa, nko kwambara amadarubindi y’imiti, kwambara uturindantoki twa shimi n’imyenda ikingira.

- Kujugunya imyanda: Imyanda ivangwa n’umuti ukwiye kandi ikajugunywa n’ikigo cyujuje ibyangombwa bisabwa hakurikijwe amabwiriza y’ibanze.

Mbere: Watermelon Ketone (CAS # 28940-11-6)

Ibikurikira: 2-Tridecanone (CAS # 593-08-8)
