Nitrogliserin 1847 yilda Italiyalik kimyogar Ascanio Sobrero tomonidan ixtiro qilingan. Sobrero boshqa mashhur italiyalik kimyogar Giuseppe Ascarellining shogirdi bo'lib, nitrogliserinni pikr kislotasi deb nomlangan yangi portlovchi modda tarkibini o'rganayotganda kashf etgan. Biroq, nitrogliserin o'sha davrda sanoat uchun juda beqaror edi, shuning uchun uni portlovchi modda sifatida ishlatish keyinchalik shved tadbirkor va kimyogari Alfred Nobel tomonidan ishlab chiqilgan.<|eot_id|>
