سلام دوستان كسي ميدونه naphtha crackers يعني چي؟ و به فارسي معني آن چه عبارتي مي شود؟

دوستان كسي ميدونه آيا «اپوكسيداسيون آلكن ها» در صنعت پتروشيمي كاربردي داره يانه؟؟؟

كاش از اول اين گرايش و رشته رو براي خانمه ا نميذاشتن تا حالا بعد از 6 سال تحصيل هيچ مزيتي برات نداشته باشه و سرخورده تر از قبل بشي. من كه اميدمو براي كار خوب تو اين رشته از دست دادم. همه جا خانمهاي مهندس شيمي رو مثل شيميست ها براي كار در آزمايشگاه استخدام ميكنن و البته با توجه به شرايط كاري...
