Subsequent elution with a methanolic solution containing 1% hydrochloric acid gives 2 -methylamino-2-(p-hydroxyphenyl)-cyclohexanone, M.P. 157-158 (decomposition), whose hydrochloride has M. P. 213 -214℃.
使用含有1%鹽酸的甲醇溶液進行后續(xù)洗脫，產(chǎn)生2 -甲氨基-2 -（對羥苯基）-環(huán)己酮，其熔點為157℃ ~158℃（分解），其鹽酸鹽熔點為213℃ ~214℃。
After evaporation of the decalin under reduced pressure, the residue is extracted with dilute hydrochloric acid, the solution treated with decolorizing charcoal, and the resulting acidic solution is made basic.
在低壓下蒸發(fā)萘烷后，使用稀鹽酸提取殘留物，使用脫色木炭處理溶液，并使產(chǎn)生的酸性溶液堿化。
Genetic constructs of the invention include a gene promoter sequence and a sequence encoding a plant F—box protein that is functionally linked to a seed-specific gene promoter to produce the effect.
該發(fā)明的基因結(jié)構(gòu)包括一個基因啟動子序列和一個能夠編碼一種F-box型植物蛋白的序列，后者可以與一個種子特異性基因啟動子連接進行這種編碼。
Genetic optimization of biomass is necessary to improve the rates and final yields of sugar release from woody biomass.

Fluorescent tags can be detected using fluorescence microscopy or cytometry, and colorimetric dyes can be detected visually or using absorbance spectroscopy.
利用熒光顯微法或細胞計數(shù)法可以檢測熒光標(biāo)記，通過視覺觀察或吸光度光譜法可以檢測比色燃。
The novel aspect of this invention is the extraction of the acids from the fermentation broth into ethanol, eliminating several purification steps required to separate carboxylic acids without needing to purify succinic acid as an intermediate.
這種發(fā)明十分新奇。它能從、發(fā)酵液中提敢酸類物質(zhì)，然后轉(zhuǎn)化成乙醇。乙醇的生產(chǎn)需要純化，且純化過程需要在不必純化 作為中間產(chǎn)物的琥珀酸的前提下分離出羥酸，而這種發(fā)明減少了幾步純化的步驟。
A sealed tube containing 5.0 g (0.026 mol) of 2 - methyl - 2 - methy1 aminobutyrophenone is heated at 185%： for ten hours and worked up using the procedure followed in Example 2. From the reaction is isolated crude 2-methyl amino - 2 - phenyl - 3 - pentanone; B. P. 59 -60 °C.(0. 1 mm.).
在185℃下，將含有5.0克（0. 026摩爾）的2-甲基-2-甲氨基丁酰苯的密封管加熱10小時，并通過示例2中的流程對該密封管進行處理。從反應(yīng)中分離出2-甲氨基-2-苯基-3-戊酮原料；其沸點是59℃~60℃（0.1毫米）。
