Abstract

Description
a)製品を遠心分離して上澄みを除去し、固形分を好適な溶媒でリンスし、低圧の場合はオーブンで乾燥する。
b)低圧で反応混合物を濃縮し、残渣を好適な有機溶媒で希釈し、濾過し、濾液を同じ溶媒でリンスし、低圧の場合はオーブンで乾燥する。
c)前記方法a)及びb)で、反応の終期又は乾燥工程の代替として、前記混合物に直接スプレイ乾燥又はターボドライイングを使用する。
ベンジルアルコール(403g、3.88モル)、酢酸(90g、1.51モル)及びチタンテトライソプロポキシド(106.7g、0.375モル)を、バブルコンデンサを装着した1000mlのフラスコ中、室温で、機械的攪拌により混合する。該混合物を、約110℃の還流温度に加熱する。5時間後に、溶液が曇り始め、徐々に濃厚になる。攪拌速度を増加させ、前記混合物を約24時間還流下に保持する。懸濁物が流体になり、強い白色を示す。前記混合物をフラスコに移し、粘性の高いペーストになるまで、約70℃で減圧濃縮(0.5mmHg)する。エタノールで、続いてジイソプロピルエーテルで得られた残渣を、次いで濾過し、低圧で乾燥し、特性をXRPD(図1a)及びTEM(図1b)に示したTiO2(26.5g)が得られる。
酢酸の代わりに、安息香酸(184g、1.51モル)を使用したこと以外は、実施例1と同じ操作で、TiO2を製造する。その特性であるXRPD(図2a)及びTEM(図2b)を示す。
酢酸の代わりに、オレイン酸(76.26g、0.27モル)を使用したこと以外は、実施例1と同じ操作で、TiO2を製造する。その特性であるXRPD(図3a)及びTEM(図3b)を示す。
オクタン−1−オール(106.8g、0.82モル)、酢酸(15.6g、0.26モル)及びチタンテトライソプロポキシド(19.3g、0.068モル)を、バブルコンデンサを装着した250mlのフラスコ中、室温で、機械的攪拌により混合する。該混合物を、約110〜125℃の還流温度に加熱する。5時間後に、溶液が曇り始め、徐々に濃厚になる。攪拌速度を増加させ、前記混合物を約24時間還流下に保持する。懸濁物が乳白色になり、粉末が沈殿する。前記混合物をフラスコに移し、約70℃で減圧濃縮(0.5mmHg)すると、純白でない粉末であるTiO2(5g)が得られる。その特性であるXRPD(図4a)及びTEM(図4b)を示す。
[実施例5]
2−エチル−ヘキサン−1−オール(106.8g、0.82モル)、酢酸(15.6g、0.26モル)及びチタンテトライソプロポキシド(19.3g、0.068モル)を、バブルコンデンサを装着した250mlの四つ首フラスコ中、室温で、機械的攪拌により混合する。該混合物を、約115〜125℃の還流温度に加熱する。約4時間後に、溶液が僅かに曇り、薄い青の色合いになる。前記反応を約20時間115℃に保持する。次いで室温に冷却する。懸濁物が乳白色になり、粉末が沈殿する。前記混合物をフラスコに移し、約70℃で減圧濃縮(0.5mmHg)すると、くすんだ純白でない、容易に分離できる凝集物である粉末であるTiO2(5.1g)が得られる。その特性であるXRPD(図5a)及びTEM(図5b)を示す。
ベンジルアルコールの代わりに、4−メトキシベンジルアルコール(113.3g、0.82モル)を使用したこと以外は、実施例5と同じ操作で、TiO2を製造する。その特性であるXRPD(図6a)及びTEM(図6b)を示す。
