موش کاتالیزگر

چهارشنبه 13 دی 1391

نوع مطلب :

پلاستیك در سال 1850 ودر شبی كشف شد كه یك گربه موشی را روی میزهای آزمایشگاه دنبال می كرد. به خانه یك شیمیدان آلمانی آدولف اشپیتلر موش زده بود بنابراین او گربه اش را به خانه آورد. گربه به یك شیشه فرم آلدئید –ماده بدست آمده از زغال سنگ-برخورد كرد. كمی از این فرمالدئید را روی پنیر متصل به تله موش پاشید. فردای آن روز اشپیتلر كه ریخت وپاش را تمیز می كرد در یافت كه پنیر مانند سنگ سخت شده است. او كه كنجكاو شده بود،فرم آلدئید را با شیرمخلوط كرد. نتیجه این كار،كازئین بود یعنی نخستین پلاستیك جهان.
