Experimental Materials and reagents ZSO was provided by a local company located in Hancheng, Shaanxi Province, China. This is a high yield area for Z.bungeanum Maxin. The chroma value of rough ZSO was 57. Peroxide and other chemicals were of analytical reagent grade and made from Tianli chemistry reagent Ltd of Tianjin city. Method Decoloration by peroxide Single factor test. The reaction was affected by many factors, such as peroxide content,reaction temperature, and reaction time. The factors can be optimized by conventional one factor-at-a-time method and statistical methods. Conventional methods involve changing one independent variable at a time while keeping other factors at a fixed level. Orthogonal test. Orthogonal test design was based on the principle of statistical mathematics,and the tests were arranged scientifically to solve multiple factor optimization requirements with reduced numbers of tests conducted. The influence of methanol-to-oil molar ratio, catalyst concentration, reaction temperature, and reaction time was tested. |

實驗部分： 材料和試劑 花椒籽油是由陜西韓城的當(dāng)?shù)匾患夜咎峁┑摹Ｔ摰厥侵袊ń返闹饕a(chǎn)地之一�；ń纷延驮偷纳戎禐�57。過氧化物和其他的化學(xué)物質(zhì)購自天津天利化學(xué)試劑有限責(zé)任公司，且均為分析試劑級。 方法 過氧化物脫色 單一因素研究。該反應(yīng)受很多因素的影響，例如過氧化物含量，反應(yīng)溫度，以及反應(yīng)時間。這些因素可以通過傳統(tǒng)的逐一要素優(yōu)化法和統(tǒng)計學(xué)方法進(jìn)行優(yōu)化。常用的方法是，一次改變一個變量，同時保持其他變量值不變。 正交試驗。正交試驗是基于統(tǒng)計數(shù)學(xué)的原理進(jìn)行的，并通過科學(xué)的安排以滿足對多種要素優(yōu)化的需求，同時還要使得進(jìn)行的研究組數(shù)盡可能少。我們對甲醇與油的摩爾比，催化劑濃度，反應(yīng)溫度以及反應(yīng)時間的影響都進(jìn)行了分析測試。 |
