화학적 성질
liquid용도
tert-Butyl acetoacetate is used as intermediate for the syntheses of different organic chemicals. Raw material in pharmaceutical Industry, In agrochemical industry. Reagent for Acyloin synthesis and ?,β - unsaturated ketones synthesis.일반 설명
tert-Butyl acetoacetate (t-BAA) is a cheap and easy to store commercial reagent. Reaction demonstrated that the more hindered tert-butyl acetoacetate (t-BAA, la) is ca.15-20-fold more reactive than the more commonly used methyl or ethyl analogs. It is widely employed as an acetoacetylating reagent.Purification Methods
Distil it under reduced pressure through a short column. [Lawesson et al. Org Synth Coll Vol V 155 1973, Lawesson et al. Org Synth 42 28 1962, Beilstein 3 IV 1536.] HARMFUL VAPOUR.아세토아세트산터셔리부틸에스테르 준비 용품 및 원자재
