| 簡(jiǎn)述了樅酸的性能與用途，微波加熱的特點(diǎn)和優(yōu)點(diǎn)，及在微波輻射的條件下從松香中提取樅酸的工藝方法，并討論微波輻照功率、微波輻照時(shí)間及催化劑用量對(duì)樅酸提取的影響情況，并找出微波輻照條件下，提取樅酸的最優(yōu)工藝方案。經(jīng)過實(shí)驗(yàn)得到本工藝的最優(yōu)反應(yīng)條件：催化劑HCl的用量為1.2mL、微波功率為616W、微波輻照時(shí)間為40min。綜合各個(gè)最優(yōu)因素，做檢驗(yàn)實(shí)驗(yàn)，得到樅酸得率為20.1%，熔點(diǎn)為170℃，比旋光度為-103.8的樅酸產(chǎn)品。 |

The performance and purpose of abietic acid was introduced in the paper, as well as the property and advantage of microwave heat, technological process of abietic acid extraction from colophony under microwave radiation. The effect of power, time used of microwave radiation and amount of catalyzer on abietic acid extraction were also discussed. Under microwave radiation, the optimum condition for extracting abietic acid can be found. The optimum reaction condition of this technological process was obtained from experiment: 1.2mL of HCl as catalyzer; 616W of microwave power; 40min of microwave radiation time. Abietic acid product of 20.1% of recovery , 170℃ of melting point and -103.8 of specific rotation was obtained from testing that was implemented on basis of all optimized factors. keywords:catalyzer;time |
