Isoamyl alcohol is an important intermediate for the synthesis of spices, pesticide and pharmaceutical products such as raw materials, but also can be an important raw material for the synthesis of rubber. Along with the people of isoprene and application scope expands, demand is also rising. This design uses isobutene and formaldehyde as raw material, with dibasic sodium phosphate as Prins condensation catalyst, synthesis of 3 methyl 3 butene 1 alcohol , and then isomerization reaction generate isopentenyl. The whole process includ the material balance, energy balance, equipment design and selection, economic benefits and evaluation, and gives the flow chart, the map of major equipment and workshop layout. Keywords: prenyl alcohol。isomerization reaction。 process design。 目錄 第 1章 綜述 .................................................................................................................... 1 前言 .......................................................................................................................... 1 異戊烯醇的性質(zhì) ................................................................................................. 1 異戊烯醇的用途 ................................................................................................. 1 異戊烯醇的市場(chǎng)分析 .......................................................................................... 2 原料簡(jiǎn)述 ............................................................................................................ 3 化學(xué)化工學(xué)院畢業(yè)設(shè)計(jì) iii 異丁烯 ..................................................................................................... 3 多聚甲醛 ................................................................................................. 3 第 2章 工藝概括 ............................................................................................................. 5 生產(chǎn)方法的評(píng)選 ................................................................................................. 5 異丁烯法 ................................................................................................. 5 異戊二烯法 .............................................................................................. 5 丙酮法 ..................................................................................................... 5 生產(chǎn)工藝流程 ..................................................................................................... 5 .................................................................................................. 6 第 3章 物料衡算與能量衡算 ............................................................................................ 8 物料衡算 ............................................................................................................ 8 物料衡算的依據(jù) ....................................................................................... 8 Prins 縮合反應(yīng)的物料衡算 ................................................................... 9 .............................................................................. 10 Prins 異構(gòu)化反應(yīng) 的物料衡算 ...............................................................11 能量衡算 ........................................................................................................ 12 1Q 的計(jì)算 .............................................................................................. 13 3Q 的計(jì)算 ............................................................................................ 14 4Q 的計(jì)算 ............................................................................................. 15 5Q 、 6Q 的計(jì)算 .................................................................................... 15 2Q 的計(jì)算 ............................................................................................. 16 第 4章 工藝設(shè)備的工藝設(shè)計(jì)與選型 ............................................................................... 17 設(shè)備工藝設(shè)計(jì)與選型 ........................................................................................ 17 設(shè)備工藝設(shè)計(jì)與選型的原則 ................................................................... 17 設(shè)備工藝設(shè)計(jì)的主要工作內(nèi)容 ................................................................ 17 反應(yīng)釜的設(shè)計(jì) ................................................................................................... 17 確定筒體和封頭 ..................................................................................... 18 ................................................................ 18 釜體和夾套的強(qiáng)度計(jì)算 .......................................................................... 19 支座的選取計(jì)算 ..................................................................................... 20 人孔的選擇和補(bǔ)強(qiáng)圈 .............................................................................. 21 接管和法蘭的選擇 ................................................................................. 21 ............................................................................................ 22 冷凝器 ............................................................................................................. 23 ....................................................................................................... 24 第 5章 生產(chǎn)車間設(shè)計(jì) .................................................................................................... 25 廠址的選擇 ..................................
